First, it investigates the factors affecting the performance criteria and working architecture of Ad hoc ondemand Distance Vector (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA). Second, it considers proposing a scenario of multi ad hoc network domains and their inter-communication using above three routing protocols separately. The simulation results show that throughput for AODV is better than both DSR and TORA by 50%. AODV has 25% lower delay than DSR and 50% lower than TORA for large number of nodes (20 nodes). The simulation is based on the application scenario model implemented on Opnetworks 10.5. It later suggests enhancement to overcome possible shortcomings observe in real life application scenario.

Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network. A MANET is a type of ad hoc network that can change locations and configure itself on the fly. Some MANETs are restricted to a local area of wireless devices (such as a group of laptop computers), while others may be connected to the Internet. The set of applications for MANETs is diverse, ranging from small, static networks that are constrained by power sources, to large-scale, mobile, highly dynamic networks. The design of network protocols for these networks is a complex issue. Regardless of the application, MANETs need efficient distributed algorithms to determine network organization, link scheduling, and routing.

The proposed on-demand link weight (ODLW) routing protocol is targeted for real-time multimedia applications where QoS parameters such as bandwidth, delay and node lifetime are considered. The ODLW is essentially a succession of on-demand and link-state routing protocols. It was shown that the unique route discovery mechanism of the ODLW outperformed Dynamic Source Routing protocol (DSR) and Optimized Link State Routing Protocol (OLSR) in reducing the end-to-end delay by 80% and 40% respectively as well as the packet drop by 30% and 20% respectively. The simulation is based on the application scenario model implemented on Opnetworks 11.0.

This paper proposes a novel routing technique called Adaptive Link-Weight (ALW) routing protocol. ALW adaptively selects an optimum route on the basis of available bandwidth, low delay and long route lifetime. The technique adapts a cross-layer framework where the ALW is integrated with application and physical layer. The proposed design allows applications to convey preferences to the ALW protocol to override the default path selection mechanism. The results confirm improvement over AODV in terms of network load, route discovery time and link reliability.
