A novel approach to improve network lifetime in WSN by energy efficient packet optimization

Wireless sensor network is a rapid developing area with diverse applications. Smartness and interoperability of network keeps it in high demand and hence comes need for the efficiency of the system. The most important limitation on sensor node is the low power consumption. Sensor nodes carry inadequate, generally irreplaceable power sources. Therefore, while traditional networks aim to achieve high quality of service (QoS), wireless sensor network protocols must emphasis predominantly on power conservation. The predominant cause of energy utilisation in a sensor network is due to the communication taking place among the various nodes while transmitting the data to the base station. This energy consumption is often directly proportional to the size of the packet and the distance between the various nodes participating in the communication. This paper presents a novel scheme to improve the lifetime of a sensor node by optimising the size of the packet such that there is no loss of data along with providing an increased lifetime for the nodes.
