Energy efficient routing protocols in mobile ad hoc networks

Energy efficiency is a major issue in mobile ad hoc networks (MANETs) in which the nodes depend on restricted power and computational resource. The energy efficiency of a routing protocol can be effected either by the complexity of the routing process or by the adversarial activities. Some of the route discovery processes involve in redundant rebroadcasts of route-request packets, thus, leading to excess energy consumption. Several energy efficient routing protocols are suggested in mobile ad hoc network to increase the lifespan of the nodes. An energy-efficient algorithm can be applied to any of the existing routing protocols and make the protocol more efficient. A general solution to deal with the fast energy exhaustion is to increase the number of nodes in the network.

Solution in NS2

  • In NS2, energy model is applied to the network, to perform the routing operations on the basis of energy.

  • High energy routers are selected for forwarding the data.

  • Residual Energy of the nodes can be calculated during the network operation in order to avoid the involvement on low energy nodes in the routing process

  • Energy consumption of the network can be calculated to evaluate the performance of the routing protocol

  • At the end of the simulation, the percentage of the alive nodes can be calculated. The higher percentage of the alive nodes indicate the improvement in network lifetime.

  • The efficiency of the various routing protocols can be compared and illustrated using graphs. Routing without considering energy reduces the network lifetime.
