Eneregy Efficent Multicast Routing in Wirless Sensor Networks: A suggested protocol

A wireless sensor network is made of a large number of sensor nodes in a specific area. Each of them has the ability to gather data from environment. And data gathered will be sent to the sink node. Energy problem is a key issue foe Wireless Sensor Network. Clustring in wireless sensor networks is one of the effective ways, which optimizes energy consumption and extends the life time of sensor networks. Clustering to group a number of nodes to from a cluster that managed by the cluster head. The cluster head is selected by considering nodes residual energy as well as the distance between this node and its neighbors. Therefore, the cluster heads that have minimum residual energy change to ordinary nod and will select a new cluster head with high residual energy. The main goal of clustering algorithms is to minimize the energy consumption and enhance the network lifetime of wireless sensor networks. Our proposed protocol, LEACH protocol conversion protocol is geographically of name GDEDBS. The main goal of this network is to collect information about the surrounding environment. One of the challenges in sensor networks, routing and transmission of data collected in these networks that are very important. In this article, a new method based on hierarchical structure (clustering) is introduced that the network is divided into several layers and each layer can be created clusters. Two Factors, energy levels and Latitude of each node in each layer are used to select Cluster heads. Then, Cluster heads using the Multi hop routing to transmit information to the base station. By applying this algorithm to a considerable extent the use of both energy and bandwidth constraints that are important in sensor network can be improved. Proposed algorithm was tested under the simulation introduced, and the results of it have been compared with LEACH that is a basic of the hierarchical method.
