Abstract: -This paper presents the energy efficient approaches and the importance of Altruistic approach in the absence of nearest neighboring nodes to the receiver. Two energy-efficient approaches have been proposed one is in-situ energy efficient approach, and the other is altruistic energy efficient approach. In the first approach existing nodes in network are only used and in second approach additional nodes called altruists are used. Generally comparison is done with five protocols with respect to these approaches and identifies altruistic DISH to be the right choice since it conserves 40-80 percent of energy, maintains the throughput advantage, and the cost efficiency compared to protocols without this approach is two times more. Our study also shows that an in-situ energy efficient approach is suitable only in certain confined scenarios. When transmit-receive pair wishes to initiate communication, neighboring nodes share their knowledge of channel usage. This helps to considerably reduce collisions and increases throughput significantly. However, it comes at the cost of increased energy consumption since idle nodes have to stay awake to overhear and acquire channel usage information. In fact this can be as high as 264% of a power-saving protocol without cooperation. The core idea is to introduce specialized nodes called altruists in the network whose only role is to acquire and share channel usage information. All other nodes, termed peers, go in to the sleep mode when idle due to this power consumption will be less. This altruistic approach seems to be complicated because it needs additional nodes to be deployed.
