Conventional routing algorithms in mobile ad hoc networks (MANETs), i.e., multi-hop forwarding, assume the existence of contemporaneous source-destination paths and are not scalable to large networks. On the other hand, in delay tolerant networks (DTNs), routing protocols use the mobility- assisted, store-carry-forward paradigm which allows delivery among disconnected network components. Adaptive...
Based on the relations of the QoS parameters in wireless ad hoc networks, we proposed a new route found mechanism. The new mechanism calculate the length of the routing, the throughput require of the data transmit as bandwidth, and by the most of the bandwidth require to resource reservation to meet the QoS. Simulation result shows that it can meet the QoS require if the network allow.
In this paper, we investigate the issues of survivability and efficiency in a heterogeneous mobile ad hoc network (MANET) and Sensor network as a combined network where the communications is achieved using a mixed MANET and Sensor Network, referred to as SMANET for supporting mission critical applications. Using the cluster managed SMANET where, heterogeneous nodes with different capabilities and...
This paper proposes cost-aware multihop handover in multihop radio access network, where multihop handover is performed based on a cost function, which is a weighted sum of hop count and the inverse of minimum available bandwidth. Then the performance of the proposed handover is analyzed via NS-2 simulation. Simulation result shows that there is tradeoff between the previous handovers and the proposed...
This article proposes a scheme for bandwidth allocation in wireless ad hoc networks. The quality of service (QoS) levels for each end-to-end flow are expressed using resource-utility functions, and our algorithms aim to maximize aggregated utility. The shared channel is modeled as bandwidth resources defined by maximal cliques of mutual interfering links. We propose an entirely novel resource allocation...
