Survey On Coverage And Energy Consumption Problem In Wireless Sensor Network

As wireless sensor networks continue to attract more attention ,new ideas for application are continually being developed many of which involve consistent coverage of a given surveillance area.. Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness, coverage and security are major consideration. Most of the attention, however, has been given to the routing protocols since they might differ depending on the application and network architecture. The sensor nodes of wireless network are constrained by limited computational, memory and energy resources and they being the battery powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network lifetime can be extended. This paper presents a survey on the two most important issues which have a great impact on the performance of wireless sensor network – Coverage and Energy Consumption. This paper also presents various routing protocols of wireless sensor networks along with their comparative analysis.
