Nodes in sensor networks often encounter spatially-correlated contention, where multiple nodes in the same neighborhood all sense an event they need to transmit information about. Furthermore, in many sensor network applications, it is sufficient if a subset of the nodes that observe the same event report it. We show that traditional carrier-sense multiple access (CSMA) protocols for sensor networks do not handle the first constraint adequately, and do not take advantage of the second property, leading to degraded latency as the network scales in size. We present Sift, a medium access control (MAC) protocol for wireless sensor networks designed with the above observations in mind. We show using simulations that as the size of the sensor network scales up to 500 nodes, Sift can offer up to a 7-fold latency reduction compared to other protocols, while maintaining competitive throughput.
1 Introduction
Every shared wireless communication channel needs a medium access control (MAC) protocol to arbitrate access to the channel. Over the past several decades, many MAC protocols have been designed and several are in operation in wireless networks today.
While these protocols work well for traditional data workloads, they are inadequate in emerging wireless sensor networks where the nature of data transmissions and application requirements are different. This paper argues that wireless sensor networks require a fresh look at MAC protocol design, and proposes a new protocol that works well in this problem domain by taking advantage of application requirements and data characteristics.We start with an example of a real sensor network.
Machine room monitoring. A fire in a basement machine room of the computer science building triggers a number of redundant temperature and smoke sensors to begin reporting the event. They all simultaneously become backlogged with the sensor reports and

Scenario 1

...Scenario 1 1.) What should Bryan do about the clock? Bryan should explain to his wife Nina what could happen if his boss found out about the clock. He should explain the ethics policy set in place at his job and that he could lose his job if word got back of them accepting the clock. Finally he should explain to her that he is looking out for the company’s reputation as well and wants to behave in an ethical manner. Stressing the fact that “ethical buyers do not accept outside gifts or favors that violate their firm’s ethics policy”( Handfield, Giunipero, Monczka, & Patterson, 2011). Another approach would be to direct her to the standard guidelines in the code of ethics developed by the Institute of Supply Management (ISM). 2.) What does the Institute of Supply Management (ISM) code of ethics say about accepting supplier favors and gifts? The ISM code of ethics strictly frowns upon accepting gifts or favors from potential suppliers. “People engaged in purchasing should not accept from any supplier or prospective supplier any money, gift, or favor that might influence, or be suspected of influencing, their buying decisions” (Handfield, Giunipero, Monczka, & Patterson, 2011).Any gifts received should be returned immediately and as discreetly as possible to avoid embarrassment on the supplier’s part. If embarrassment does occur a buyer should still not feel obligated to accept the gift or favor because of its effect on the suppler. 3.) Why do you think the supplier sent the...

Middle Managers

...organisation's senior leadership on one hand and the ground personnel on the other. These managers are responsible for the implementation of the organization's strategy on a day-to-day basis and it would be safe to say that a company's success or failure largely depends on the strength of this cadre. A strong middle management also provides organisations with a pipeline of future leaders. Besides, a strong managerial cadre also offers the added benefits of providing much needed continuity and low attrition. I have seen that middle level managers typically face their own set of challenges. In organisations that I have worked or where I now provide advice, I have always seen that if these challenges are left unidentified or unaddressed they almost always lead to disgruntlement and low motivation which can then, over a period of time, seep in to the front end. What are the challenges that mid-level managers face? 1. Transition from worker to manager: Most managers take time to settle into their leadership role after being promoted from the ranks. They grapple with the difference between doing things and getting things done. In one instance, it was seen that a star salesperson who was promoted to a sales manager could not manage the transition at all. His micromanaging ways upset his team and despite repeated counseling, he could not outgrow this habit. Privately, some senior leaders admitted to me that they had visualized that this could happen, but were really in no position to deny...

Employee Empowerment

...empowerment is a management decision based on proven capability and demonstrated trust by the employee. Transformed organizations introduce empowerment over rules and regulations through smart governance and guidelines supporting organizational culture. These practices promote improved customer service through employee decision-making extended by management authority and flexibility. Demonstrating customer-focused programs and practices through skilled and knowledgeable employees with authority and responsibility to move the organization forward in its mission. Power and Empowerment By definition and context, power is “possession of control, authority, or influence over others” (Merriam-Webster's Third New International Dictionary Unabridged, 2002). A good manager can have power and influence over others and lead well. The definition of empowerment is “to give authority, to enable, and to promote influence” (Merriam-Webster's Third New International Dictionary Unabridged, 2002). The act of empowerment allows a manager to enable individuals to think and act in a way that will enhance their performance, and demonstrate trust in the employee’s abilities. This does not remove power from the manager but instead increases his or her potential to gain power by an effective team. Flat Organization Model Organizational structure is the key difference in reporting processes in organizations. Big organizations have vertical organizational structures with many management layers between...

Centralisation and Decentralisation

...head office/head quarters. Centralisation The main decisions are made by senior management, where little authority is passed down the organisation. Advantages • Decisions are made by experienced people with an overview of the company. • Ensures policies are consistent throughout the company. • Ensures quick decisions can be made without consultation. • Procedures such as ordering and purchasing can be standardised throughout the company, leading to economies of scale. • In times of crisis the firm may need strong leadership by a central group of senior managers. Disadvantages (mainly advantages of decentralisation) • Centralisation reduces the input of the day to day experts, e.g., the shop floor staff, into the firms’ decision making. • It risks demoralising branch managers who may feel mistrusted or powerless. Decentralisation Decisions are made by junior management as authority is passed down the organisation, thereby accepting less uniformity in how things are down. There has been a trend in the 1980s and 1990s is to decentralise to provide greater flexibility. An example of a decentralised structure is Tesco the supermarket chain. Each store of Tesco has a store manager who can make certain decisions concerning their store. The store manager is responsible to a regional manager. Advantages • Reduces the stress and burdens of senior management • It can empower local managers encouraging them to be more innovated and...

...use the MBO method to accurately measure employee performance in the following occupation, secretary, engineer, and directory assistance officer. Management by Objectives (MBO) is a process in which a manager and an employee agree upon a set of specific performance goals, or objectives, and jointly develop a plan for reaching them. The objectives must be clear and achievable, and the plan must include a time frame and evaluation criteria. For example, a salesperson might set a goal of increasing customer orders by 15 percent in dollar terms over the course of a year. MBO is primarily used as a tool for strategic planning, employee motivation, and performance enhancement. It is intended to improve communication between employees and management, increase employee understanding of company goals, focus employee efforts upon organizational objectives, and provide a concrete link between pay and performance. An important factor in an MBO system is its emphasis on the results achieved by employees rather than the activities performed in their jobs The principle behind management by objectives is to make sure that everybody within the organization has a clear understanding of the objectives of the organization. Also being aware of their roles and responsibilities.
