“…RandomCast: RandomCast (Lim et al, 2009) is a new communication mechanism, in which a sender can specify the desired level of overhearing, making a prudent balance between energy and routing. RandomCast is highly energy-efficient compared to conventional 802.11 as well as 802.11 PSM-based schemes, in terms of total energy consumption, energy goodput and energy balance.…”

“…Overhearing improves the routing efficiency in DSR by eaves dropping other communications to gather route information but it spends a significant amount of energy. In the Random Cast mechanism (Lim et al, 2009), a node may decide not to overhear i.e., a unicast message and not to forward i.e., a broadcast message when it receives an advertisement during an ATIM window, thereby reducing the energy cost without affecting the network performance. In addition to the energy consumption, overhearing brings in several undesirable features.…”

Problem statement:The main idea is to design an energy efficient algorithm for reducing the amount of overhearing based on RSS value in a Mobile Ad-hoc Network (MANET). Approach: A cross layer framework is designed by combining the physical, MAC and network layer. RSS value is taken from the physical layer and it is used for finding the Mobility Parameter (MP). MP value determines the level of overhearing and rebroadcast probability. The energy conservation is achieved by integrating the 802.11 PSM with DSR. In 802.11 PSM, all the nodes are in low power sleep state, but the disadvantage here is unconditional overhearing. So, a conditional overhearing mechanism is proposed based on mobility parameter to reduce the energy consumption. This mechanism reduces energy consumption but at the same time, the node mobility results in more stale routes in route cache of DSR over a period of time. This occurs due to the lack of route cache updation. In the proposed design, RSS value determines whether to select the link or not prior to the route discovery process. Results: Simulation results are compared for Packet Delivery Ratio (PDR) and energy consumption. MP based conditional overhearing shows a 3.2% PDR improvement. It achieves a 20% power saving, if the pause time crosses 300 sec. For the packet injection rate of 2 packets/sec, under no mobility condition, it utilizes 50 joules lesser energy consumption compared to Random Cast. Conclusion: The NS-2 simulation results reveal that the proposed work is energy efficient by reducing the amount of overhearing and also it eliminates the stale routes compared to the classical methods.

Energy efficiency is a measure of the performance of IEEE 802.11 wireless multihop ad hoc networks. The IEEE 802.11 standard, currently used in wireless multihop ad hoc networks, wastes bandwidth capacity and energy resources because of many collisions. Therefore, controlling the contention window size at a given node will increase not only the operating life of the battery but also the overall system capacity. It is essential to develop effective backoff schemes for saving power in IEEE 802.11 wireless multihop ad hoc networks. In this paper, we propose an energy-efficient backoff scheme and evaluate its performance in an ad hoc network. Our contention window mechanism devised by us grants a node access to a channel on the basis of the node's percentage of residual energy. We use both an analytical model and simulation experiments to evaluate the effective performance of our scheme in an ad hoc network. Our extensive ns-2-based simulation results have shown that the proposed scheme provides excellent performance in terms of energy goodput, endto-end goodput, and packet delivery ratio, as well as the end-to-end delay.

Mobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and prominent routing protocol which may satisfy the above said issue. While making routing process in traditional AODV,onlyone route information will be sent as reply in the reverse path. This reply from the destination may be lost due to fast mobility of modes which in turn leads to the retransmission of route request packets to establish routes.The main cause of this problem is increased communication delay and reduction of several QoS metrics. The main goal of the new Novel QoS aware reliable routing algorithm is to send multiple route replies and establishes reliable data transmission between source and destination. The new NQARR-AODV protocol establishes paths on-request using a reliable reverse pathestablishment method. During pathestablishmentphase, the source node first sends the route requests through all available paths to the destination. The destination node,upon receiving the path requests,inturn rebroadcasts the reverse path requestsas like sender node has done. Upon receiving the multiple route replies from the destination, a path with high reliability is choosen by the source node using the three parameters, the MAC overhead, the Eminence of Link, node residual energy. NQARR-AODV path establishment method works well and requires only minimum steps. It also provides high energy efficiency and load balancing thus prolongs the network life time and makes up high reliability communications. The experimental values prove that the NQARR-AODV algorithmis more reliable and stable and outperforms AODV by reducing energy consumption, overhead and delay. Also NQARR-AODV gains bestratio of packets delivered than that of normal AODV. In our proposed NQARR-AODV protocol, the source node can find QoS aware reliable route to the destination.
