Four Modified Routing Protocols for Increasing Lifetime of Sensor Network

Sensor networks are systems with restrict resources that are scattered on a large scale with numerous deployment density and are used in aggregating data in a intelligent style. In this paper the concept of "efficient energy consumption" in routing protocol of sensor network, which causes to increase the lifetime of sensor network, has been studied and a taxonomy of various techniques for efficient energy consumption is presented. Also four modified routing protocols are presented in a way that each routing protocol uses a special technique to consume energy efficiently. After that we have simulated these modified protocols and compared their function with recent protocols and we have observed that proposal routing protocols increase the lifetime of sensor networks drastically.
