Mobile Ad-hoc network is an autonomous system of mobile wireless nodes connected dynamically without any preexisting infrastructure. Here, since the nodes are mobile, the network topology changes rapidly and unpredictably over time. The QoS routing has challenging problems due to the network's dynamic topology. The multi hop wireless forwarding of packets,(More)
Ad hoc networks are frequently established in insecure environments and hence become susceptible to attacks. A number of recently proposed secure routing protocols entail a number of prerequisites during both the network establishment and operation phases as they employ cryptographic algorithms. In contrast, trust-based routing protocols locate trusted(More)
The success of next generation wireless networks will rely much on advanced mechanisms for seamless mobility support among emerging heterogeneous technologies. Currently, mobile IP is the most promising solution for mobility management in the Internet. Several IP micro mobility approaches have been proposed to enhance the performance of Mobile IP which(More)
Reducing power consumption and increasing battery life of nodes in an ad hoc network requires an integrated power control and routing strategy. The power control is achieved by new route selection mechanisms for MANET routing protocols, which we call energy-based time delay routing (EBTDR) and highest energy routing (HER). These algorithms try to increase(More)
As laptop computers begin to dominate the marketplace, wireless adapters with varying bandwidth and range capabilities are being developed by hardware vendors. To provide multihop communication between these computers, ad hoc mobile networking is receiving increasing research interest. This paper deals with the analysis of the transmission range effects on(More)
In mobile ad-hoc network, the mobility of nodes and the error prone nature of the wireless medium pose many challenges and packet losses. Here, since the nodes are mobile, the network topology changes rapidly and unpredictably over time and produce different queuing behaviour. Hence, a scheduling algorithm to schedule the packets based on their respective(More)
