Efficient Routing with Compressive Sensing for Wireless Sensor Network

A wireless sensor network is a collection of nodes cooperative to each other and organized into a certain network. It is used in large applications to monitor the physical or environmental conditions. Agriculture and farming is one of the most important fields which uses wireless sensor network for monitoring and gathering data such as underground water resources in new cultivated lands. The energy saving is the most important parameter in wireless sensor network. In this paper, the compressive sensing with LEACH routing protocol is investigated for the purpose of increasing the lifetime of the nodes by reducing the transmitted data size. Simulation results show that node life time achieved by the proposed LEACH routing protocol with compressive sensing can be increased approximately to 1.7 times that achieved by conventional LEACH protocol.
