CDS Based Lifetime Improving In Wireless Sensor Networks And Wireless Ad Hoc Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Energy consumption and extending the lifetime of the networks plays a vital role in wireless sensor networks and wireless ad hoc networks. The sensor network is formed by connecting large number of small sensor nodes which are randomly deployed. To maximize the lifetime of the network, a graph is constructed named Connected Dominant Sets (CDS) which forms a virtual backbone of the network. In the sensor networks using CDS, failure of a single node causes to network partitioning and leads to disconnection of the network. Replacing the faulty node takes many displacements and consumes more energy. There is no effective scope in for fault detection and replacement in wireless sensor networks. The lifetime of the networks depends on the connectivity between the nodes. In this paper, we concentrate on two important factors: one is extending the lifetime of the network and energy consumption, the other one is covering the maximum area with a minimum number of sensor nodes. Replacement of the faulty dominant node is replaced by the neighbor dominant node with high residual energy.
