PERFORMANCE ANALYSIS OF MULTI-HOP ROUTING PROTOCOLS FOR WSN’S

A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions. A WSN system incorporates a gateway that provides wireless connectivity back to the wired world and distributed nodes. A key concern in WSN technology is to enhance the network lifetime and to reduce the energy consumption of the sensor network. Many routing protocols available for maximizing the network lifetime. In this paper, we have been propose a gateway based energy efficient routing protocol (GEAR) for Wireless Sensor Networks (WSNs) and also compare the performance of our protocol with LEACH (Low Energy Adaptive Clustering Hierarchy). Performance analysis and compared statistic results show that our proposed protocol perform well in terms of energy consumption and network lifetime
