Abstract-Enhancement the Performance of MANET (Mobile Ad-hoc Network) using spatial d iversity. Spatial d iversity imp lemented using cooperative transmission technique in Medium access control (MAC) layer level protocol. In noisy environment limit the network performance like coverage area, limit number of node, degrade packet transmission rate, increase packet loss rate etc. In this paper enhance the source to destination transmission range, minimize the packet loss, improve packet transmission rate and appropriate end to end delay. When direct lin k is fail to transmit packet then Cooperative scheme help to transmit packet. Cooperative scheme is to help the packet transmission with five handshakes instead of four. This scheme imp lemented in MANET network on MAC layer protocol. Cooperative scheme imp rove the performance with help of intermediate node between sources to destination. We are performance analysis using discrete simu lator NS-2 in MANET. Our performance based on MAC layer level with cooperative scheme in IEEE W LAN standard CSMA/CA protocol.

Abstract-This paper investigates the optimal power routing problem in relay-based cooperative networks, where the relays are arbitrarily positioned. We generalize the standard shortest path routing algorithm (GSPRA) to find an minimum-power distributed MIMO multi-hop route from a source to a destination while satisfying a given e2e outage probability demand. The task of the proposed approach includes how to group relays to virtual antenna array (VAA) and discover the optimal multi-hop path. Instead of using per hop (or link) constraint, which is assumed by most of the existing routing algorithm, an e2e outage probability constraint is assumed for more relevance and freedom in practical systems. Under the concept of virtual node and virtual link, an efficient power allocation solution for general distributed MIMO multi-hop networks is used to calculate link costs for the shortest path algorithm. The proposed routing approach can fully exploit the merits of both cooperative communications and multi-hop transmissions. The significant power savings due to the proposed approach in comparison to the existing algorithms is demonstrated by numerical results.Index Terms-Optimal power routing, asymmetric distributed MIMO, shortest path algorithm, outage probability, relaying.

“…In [8], the authors demonstrated that the minimum energy cooperative path (MECP) routing problem is NP-complete, and then proposed a cooperative shortest path routing algorithm to achieve nearly the MECP. In [9], the authors proposed the Minimum Power Cooperative Routing (MPCR) algorithm, which constructs the minimum-power route with certain throughput guaranteed. In [10], the authors proposed the CoopGeo protocol, which provides an efficient approach to select the next hop as well as the optimal relay based on cross-layer designed geographic routing.…”

Abstract-Cooperative geographic routing has emerged as an efficient, scalable routing paradigm that exploits the joint merit of cooperative diversity and position-aided localized operation to enhance the network performance. In terms of the hop efficiency, an existing scheme called Relay-Aware Cooperative Routing (RACR) has offered a cross-layer approach based on its quantitative study of how physical-layer cooperation leads to link-layer radio coverage extension, under the policy of equal power allocation (EPA) over the cooperating nodes. However, the effect of cooperation-based radio coverage extension dramatically varies with the power allocation policy in use. In this paper, we extend the RACR scheme by addressing a power-optimized cooperative geographic routing problem. With the joint optimization of relaying position and power allocation, the maximum cooperative transmission range is derived. We then, according to the result, present a modified cross-layer routing protocol taking into account the effectuation of optimal power allocation (OPA). Simulation results show that the proposed scheme effectively improves the coverage extension performance as well as reduces the average number of hops.
