摘要：Wireless sensor networks with thousands of small sensor nodes are becoming very popular due to their large use in many of applications such as monitoring and collecting data from undisturbed dangerous environments, emergency rescue operations, military surveillance etc. But the nodes in a sensor network are severely affected by energy. Reducing the energy consumption of the nodes to increase the network lifetime is considered as a most important challenge while designing a new routing protocol. In this paper we propose a new power-aware, hierarchical protocol that utilizes the regular assignments of the cluster head role to different nodes based on the highest remaining battery capacity for confirming the equal dissipation of power by all the nodes. Transmission from a single cluster head to the base station in each ro und and the distribution of the data collection workload among all the nodes, save the cluster heads from early damage. The use of data separation also reduces the amount of information to be transmitted to the base station. NEW Protocol offers the advantage of small transmit distances for most of the nodes and thus helps them to be operational for a longer period of time by conserving their limited energy. Use of a fresh set of parameter values in each round provides the users the ease to change these values in a way to handle the power consumption. Ou r New Protocol is highly suitable for time critical applications. From the performance evaluation we observe that New Protocol outperforms other protocols in terms of energy saving, life of the network, latency and fault tolerance.
