Virtual Grid based Dynamic Route Adjustment ( VGDRA) Scheme based on Sink Mobility for Wireless Sensor Networks
International Journal for Research in Applied Science and Engineering Technology
In wireless sensor networks (WSN), to control the energy dissipation of the nodes, the use of mobile sink nodes is considered as the major solution. The mobile sink has various advantages and disadvantages as well. The data transmission in a network with mobile sink becomes difficult due to constant variations in network topology. Therefore to transmit the data from source node to sink node, the nodes need to reconstruct the route every time when sink update its location which can leads to the
... h can leads to the high energy consumption and reduction in network lifetime. In this paper a VGDRA i.e. Virtual Grid Dynamic Route Adjustment based mechanism is developed to enhance the network lifetime along with reduced delay. The strategy of Cluster head selection is enhanced by selecting the CHs on the basis of the energy and delay. After simulating the proposed work, the results demonstrate that the Network Lifetime is enhanced, network structure cost and network convergence time is reduced.
