In this research paper we are proposing a delay minimization algorithm for minimizing end to end delay for multicasting on a tree based wireless network with multiple source and multiple destinations. Our algorithm uses two stages, first is level division and second is for selecting best path among all paths from tree. The second stage is DOMA (Delay Optimal Multicast Algorithm) algorithm. Our algorithm...
A dynamic protocol stack (DPS) for ad hoc networks, together with a protocol stack construction scheme that is modeled as a multiconstrained knapsack problem is proposed. Compared to the traditional static protocol stack, DPS operates in a dynamic and adaptive manner and is scalable to network condition changes. In addition, a protocol construction algorithm is proposed to dynamically construct of...
We present in this paper a multi-layer scheme for QoS Management in MANETs. Our proposal is to combine multiple communication protocols of different layers, to provide an adapted QoS to a different traffic classes. Protocols are modified to improve their awareness of the quality of service, so that new extensions with QoS support are developed. We model QoS service at routing layer, via a QoS extension...
End-to-end delay and Communication cost are the most important metrics in MANET (Mobile Adhoc Network) routing from source to destination. Recent approaches in Swarm intelligence (SI) technique, a local interaction of many simple agents to meet a global goal, prove that it has more impact on routing in MANETs. Ant Colony Optimization (ACO) algorithm uses mobile agents as ants to discover feasible...
QoS guarantee in mobile ad hoc network is a challenging problem and has received much attention. Although the access policy with reservation of TDMA can support some QoS services, the extra delay introduced by its time multiplexed communication make it can not be adapted to large scale network. To solve the problem, we propose a heuristic optimal delay routing algorithm which chooses delay as the...
