Abstract:In this paper we address the issue of controlling transmission power in power-aware adhoc networks. We argue that minimum transmission power is not always optimal. Previous work that minimizes the transmission power does not consider both the energy consumed in collision resolution and the energy disbursed to overcome the interference resulting from neighboring nodes. We investigate the basic transmission power control for the 802.11 MAC protocol, in which the control frames and the data frames can be transmitted at different power levels. A unified collision and interference model of a uniformly distributed network is constructed. Based on this model, the end-to-end network throughput and the total energy consumption of the network are examined for different network parameters. For a net-work with a given node density, our results show the optimal transmission power for control messages and for data messages that will yield maximum throughput and minimum energy consumption per message.

-Multipath routing mechanisms have been preferred over single path routing to provide parallel fail safe paths and to maximize throughput. Applying traditional shortest path metric for multipath route selection leads to traffic concentration at some nodes resulting in congestion, thereby causing performance degradation . Interference caused due to neighbouring node traffic is another factor that further limit its performance gains. Towards this, to ease out congestion and improve network resource utilization we devise a load balancing strategy that splits the load among multiple paths according to link quality. Link quality metric is formulated considering the current load condition , traffic interference and energy of the intermediate nodes. To study the effectiveness of the proposed load distribution method we compare it with another load balancing strategy that forwards traffic along one path ,found using our link quality metric and which switches over to alternate best path on route failure. Simulation results conducted show that proposed load splitting strategy is able to achieve improvement in performance in terms of reduced latency and improved throughput. Network Life time is also improved.

“…Infrastructure networks are capable of supporting reliable communications between arbitrary nodes with routing based on optimal paths over dedicated routers along high-bandwidth links. However, providing this functionality in MANETs has an adverse effect on communication in terms of the overheads that are generated and the interference that this causes [4,9] and may not be well suited to typical MANET deployment scenarios such as those mentioned above.…”

Abstract. Service discovery protocols for mobile ad hoc networks attempt to overcome the inability to locate resources presented by networks in which prior knowledge of node identity and capability is not available. Existing approaches continue to rely on underlying address-based routing protocols in order to communicate with discovered services. These two-tier approaches generate routing overheads which negatively impact on performance and network scalability. As high-powered mobile computing devices with wireless connectivity become increasingly ubiquitous, the need for routing protocols which can operate at increased network densities becomes more acute. Cross-layer approaches to service discovery in MANETs have attempted to optimize the discovery process through direct integration with underlying routing protocols, however additional steps are necessary to improve service discovery performance, network scalability and application throughput. This paper describes the Service Discovery and Routing Protocol (SDRP), a novel service-oriented routing protocol for MANETs. This protocol eschews the use of network-wide unique addresses or underlying addressbased routing protocols and focuses instead on routing only to and from nodes which provide services. A comparison with existing approaches demonstrates that this approach improves discovery success rates and application throughput at higher node densities.
