Enhancing Energy And Life Time Of Wireless Sensor Network Based On Cluster Intra And Inter Optimum Path Routing Algorithm

Abstract

A wireless sensor network is an ad hoc network that has collection of wireless sensor nodes scattered over an area to gather physical properties such as humidity, temperature, pressure, stress and so on. This information is then forwarded to base station or sink node. The sensors battery may not be a chargeable one and when battery drains then sensor fails and new sensors are replaced. The existing LEACH protocol extends the life time of sensor by clustering concept. In our proposed system minimum numbers of sensor nodes are activated based on the area coverage and they are grouped as different cluster. In this a intra and inter optimum route path selection is established to maximize wireless sensor network life time .An intra optimum route path is established by member node to reach cluster head node within the cluster and inter optimum route path is established by the cluster head node to reach the sink node either directly or through gateway nodes present in the other clusters. A fuzzy logic is applied in optimum route path selection for selecting minimum number of nodes with sufficient energy level for transferring packets in wireless sensor networks. All nodes in the wireless sensor network should be utilized effectively so as to avoid drain in energy level of particular nodes. To estimate the performance, simulations are performed. As a result, we examine that our protocol optimum route is more efficient than the other routing protocols.
