An energy efficient multicast algorithm for an Adhoc network using network coding and MAC scheduling

Abstract

The paper envisages the network modeling of a wireless multicast network by approach of optimized joint MAC scheduling and network coding. A heuristic method of designing a network is achieved by scheduling algorithm which is based on network parameters such as interference free transmissions, and optimization of avoidable scheduling sets. We derive a joint linear optimization problem which is used in the designing of the wireless network. Further when the scheduling is done, the network coding is adapted. The code construction algorithms are used and the unequal timeshare is incorporated in designing network codes. The paper demonstrates the variation in the network performance parameters like Throughput, Energy efficiency, Delay, Packet Delivery Ratio, Overhead, and Normalized Overhead. The statistics is madeby varying the network modeling parameters with different node densities. After the network coding, based on the traffic flow, the sleep state is introduced where the network goes to the hibernated mode. A unique joint optimized structure is required for MAC scheduling and network coding. A heuristic approach of scheduling is needed to avoid hidden station problem. Also to provide an energy and throughput optimization for multi hop wireless network.
