Disruption Tolerant Networks

In Disruption Tolerant Networks (DTN), information is exchanged between mobile nodes with the same transmit power. It is an energy-consuming process and highlights the need for energy-efficient power control mechanisms. If the transmit power of nodes is too low, they might miss many of the opportunities of transmission. On the other hand, high transmit power is energy inefficient. In this paper, we propose ERBC (Energy-efficient Routing algorithm Based on Cross-layer design), an energy-efficient routing algorithm based on cross-layer design. Instead of using fixed transmit power, ERBC dynamically chooses the transmit power using both the cross-lay design and the RSSI technology. Meanwhile, ERBC broadcast data packets partially in order to enhance the delivery ratio. Through simulation, we demonstrate that ERBC can reduce 37% for per-bit energy consumption than that in basic epidemic routing protocol.

Abstract Wireless Sensor Network (WSN) is known to be a highly resource constrained class of network where energy consumption is one of the prime concerns. The existing system of LTDC has more drawbacks in network routing optimization lifetime and energy level improvement needed. In this research, a cross layer design methodology was adopted to design an energy efficient routing protocol entitled Avant-Grade framework Routing Optimization [AGFRO]. AGFRO is designed to minimize energy consumed in each node by reducing the amount of time in which a sensor node is in an idle listening state and reducing the average communication distance over the network. The performance of the proposed system has been critically evaluated in the context of network lifetime, throughput, and energy consumption of the network per individual basis and per data packet basis. The research results were analyzed and benchmarked against the well-known AGFRO protocols. The outcomes show a significant improvement in the WSN in terms of energy efficiency and the overall performance of WSN.

Hoc Networks

In ad hoc network, the topology of network changes frequently due to the mobile nature of nodes where the communication is possible without any fixed network infrastructure. Mobile nodes are battery operated and so energy efficient routing should be provided which increases the network life time. The existing routing mechanisms do not consider both hop count and energy of nodes for data transmission. In this paper we propose a routing mechanism where data transfer from source to destination is based on the minimum hop count and residual energy of mobile nodes. The proposed RPAR protocol shows better performance when compared to existing Energy power aware routing  protocol .The analysis is carried out by using network simulator (NS-2), the simulation results shows that the proposed routing mechanism provides energy efficient and reliable  routing in ad hoc networks.
