Grid Clustering and Routing Protocol in Heterogeneous Wireless Sensor Networks (Short Paper)

Abstract

In wireless sensor network, sensor nodes usually use batteries to provide energy, and energy consumption have very strict restrictions. High demands about the efficient use of energy are put forward. However typical multi to one communication mode in the wireless sensor network will lead to the uneven consumption of sensor nodes in the whole network. So it will greatly shorten the lifecycle of the entire network. As for this problem this paper optimize the model of heterogeneous chessboard clustering of sensor network and propose a grid clustering mechanism and propose an effective node routing protocol to achieve the goal of prolonging the network lifecycle by balancing the energy consumption of nodes. Simulation experiments show that the grid clustering protocol greatly improves the lifecycle of wireless sensor networks and has better performance compared with LEACH and LRS.
