advancement of the Wireless Sensor Networks (WNSs). Their usage in various fields making them the most fast evolving technology. The wireless sensor network consist of a large number of sensor nodes, Sink and the Actuator. These sensor networks use broadcast communication paradigm but most of the networks depends on point-to-point communication. The sensor networks does not have a global identification because of large in number. The communication architecture of sensor networks has three phases

channel is idle then data is transmitted otherwise transmitter has to wait for a random time. CSMA/CA protocol is used for wireless LANs in which nodes are moving and changes their states rapidly. RTS/CTS frames are used to inform the nodes about current transmission. Without RTS/CTS frames the performance of CSMA/CA protocol is degraded. Because if the all nodes involved in the network have not be informed about current transmission, the chances of collision will be increased and the nodes will collide

WIRE LESS MESS NETWORK WITH HRPU ABSTRACT A Wireless mesh network is a mesh network created through the connection of wireless access points installed at each network user’s locale. Each user is also a provider, forwarding data at next node. The networking infrastructure is decentralized and simplified because each node need only transmit as far as the next node. Wireless mesh networking could allow people living in the remote areas and small businesses operating in rural neighborhoods

APPENDIX………………………………………………………………………………………7 1. Project Description: Industrial businesses are looking for readymade laid out networks and resources to be utilized to cater their needs of remote monitoring. Human monitoring is obsolete and no longer is being considered better option. The penetration of cellular network in the rural areas made this remote monitoring better option. This proposed design will utilize wireless

Dominating Sets: Sensor Networks Prachi Shivhare, Sriraman Sridharan, Tushar Deshpande ! processing power efficiently. As a sensors battery is not replaceable its energy becomes the most important system resource. The best method for conserving energy is to put the sensors to sleep when they are not in use. At the same time the network must maintain its functionality through a connected sub-network that lets the monitoring station communicate with any of the networks active sensors. Each sensors
