Energy Efficient Routing Scheme for Wireless Sensor Network with CDMA Nodes

– The paper attempts to evolve a routing scheme with a view to improve the utilization capacity and enhance the life time of the Wireless Sensor Network (WSN). The focus charters to design a Cluster based Ad-hoc on Demand Distance Vector (CAODV) algorithm to facilitate the transfer of information in a composite network with both Code Division Multiple Access (CDMA) and non-CDMA nodes. It avails the use of a high energy node to commensurate the process and ensure a smooth flow of traffic among a host of CDMA source and destination nodes. It inscribes to be-hive the merits of CDMA nodes in enhancing the rate of data transfer and create a congenial environment for large scale transmission. The approach orients to acquire the best performance in terms of metrics with minimum expenditure of energy to foster an energy efficient routing mechanism. The Network Simulator (NS2) based simulation results obtained over specific time frames reveal the applicability of the proposed strategy in the present day context.
