Research and Implementation of Data Collection Protocol for Wireless Sensor Networks

Wireless Sensor Network is a new self-organization and multi-hop network which deploys a lot of nodes which communicating with each other wirelessly, so the design of a appropriate routing protocol for wireless sensor networks is essential. In this script, the performances of many classical route strategies are introduced and analyzed. In order to test the performance of LEACH and LEACH-C algorithm, the NS2 (Network Simulator Version 2) is used to realize the simulation of the LEACH and LEACH-C algorithm in three different scenarios and analyze the results from three angles. The result shows that, in condition that the SINK node is not far from the deployed sensors, no matter the nodes are randomly deployed or deployed in linear, LEACH-C performs much better than LEACH. In the opposite condition, LEACH will perform better than LEACH-C except in the data throughput.
