A Survey on Neighborhood Dependant Topology Control in Wireless Sensor Networks

Wireless sensor networks are the ultimate technology for communication that allows network nodes to communicate without the need for a fixed infrastructure and wires. They use electromagnetic waves, as the information transmission.The development of network technologies has prompted sensor folks to consider alternatives that reduce costs and complexity and to improve reliability. This paper addresses the issues associated with the steady connectivity which reduces the overall power consumption and a comparison study is made on these issues. A hierarchical cooperative technique is also proposed to increase the Packet delivery ratio and to reduce the overall energy consumption of the network.
