“…When the expected data rate cannot be compromised any more, traffic of Node 2 is stopped at once. Behalf of this case, we can see that the E-AODV achieves the benefits of ensuring the QoS not only at route discovery stage, but also during the transmission process [8,9].…”

An ad-hoc network is a multi-hop wireless network system where all the nodes cooperatively maintain the network connectivity without any centralized infrastructure. If these nodes in the network cannot remain in their same positions means position various dynamically, that is called a mobile ad-hoc network (MANET) system. Efficient protocols are used here to forward data packets with very low packet loss.In this paper, .an adaptive routing algorithm is proposed in MANET using modified AODV by calculating the loads on different routes using given parameters like aggregate interface queue length and nodes remaining energy. An Adhoc on Demand Distance Vector Protocol (AODV) for routing is one among the effective Reactive Routing Protocols in MANET. The objective of this paper is to basically enhance the AODV network performance, when frequent link failures in network due to mobility of the nodes. The simulations and performance analysis are carried out to evaluate the network performance using Network Simulator tool (NS-2), based on the quantitative metrics packet delivery ratio and average end to end delay. The achieved simulated result helps to understand the precise behaviour of the AODV in the distributed network environment. This paper proposed a new protocol E-AODV (Enhanced AODV) which is a modified AODV with Enhanced packet delivery ratios and minimized end to end packet delay. General TermsEnhancing the performance of AODV Routing Protocol and Compare it with other routing protocols.

“…When performing admission control in an intermediate node not only we calculate required bandwidth in that node which is on the path, but also we should consider the available bandwidth of its neighbor nodes, because as mentioned before 1 On-demand Multicast Routing Protocol 2 route request packet accepting traffic in the neighbor nodes of intermediate node, will affect on its available bandwidth. Therefore one step of admission control in each active node in routing process is checking the available bandwidth of its one-hop neighbor nodes.…”

In this paper we propose a mesh based"on demand" multicast routing protocol for Ad-Hoc networks with QoS (quality of service) and reliable multicast support. The proposed scheme has five key features: (a) it is based on the forwarding group concept (i.e., a subset of nodes is in charge of forwarding the multicast packets); (b) it dynamically refreshes the forwarding group members using a procedure similar to on demand routing;(c) it significantly reduces control overhead, and make the scalability of multicast routing protocol possible in mobile ad hoc networks by consolidation of control packets;(d) it supports QoS routing using good estimation of available and required bandwidth, and reserving required bandwidth on the end to end active routes in multicast mode;(e) it provides local recovery mechanism, which aims to reduce the control overhead and achieve fast recovery when route breakage happens.

Efficient Self-Organization in Multihop Wireless LAN

Efficient cooperation and self-organization is a fundamental challenge in distributed autonomous systems. In this paper, we study this problem in the context of multi-hop extended wireless LANs, in which a mobile user can reach the Access Point (AP) over a multi-hop relaying path through intermediate nodes.While both users and service providers can enjoy the benefits of such extended network coverage, the system must provide incentives for a selfish user to contribute its resources (battery, bandwidth, CPU, etc.) to forward packets for others. Moreover, the system efficiency depends largely on how the relaying paths are formed, which ultimately depends on the incentive mechanism in use. Our goal is to design an incentive framework that not only stimulates the selfish users to participate in packet forwarding but also leads to desirable system-wide performance in various scenarios. This is achieved by enforcing both rewards (in cases of successful forwarding) and penalties (in cases of packet losses) in the incentive model. We describe our incentive framework design and analytically study the overall system efficiency in both heavily loaded and lightly loaded cases. We further demonstrate the performance gain of our incentive model, as compared to a fixed-price packet purse model, through extensive simulations.
