Delay Tolerant Networks (DTN) are sparse ad hoc networks in which no contemporaneous path exists between any two nodes in the network most of the time. Due to non-availability of end-to-end paths, multicast protocols of traditional networks fail in DTN because they try to find connected multicast graph between source and destination nodes before forwarding data packets. Routing protocols proposed...
This paper proposes an improved retain and replace (QGDA) genetic algorithm through selecting code in the ad hoc network routing. The simulation shows that this algorithm has more superior than that of the traditional retain elites (GAES) genetic algorithm and based on information entropy IEIAE immune algorithm in the delay and control of the expenditure.
Mobile nodes in some challenging network scenarios suffer from intermittent connectivity and frequent partitions e.g. battlefield and disaster recovery scenarios. Disruption tolerant network (DTN) technologies are designed to enable nodes in such environments to communicate with one another. Recently, network coding schemes for DTN has been proposed. However, these schemes work well only in scenarios...
In wireless mesh networks (WMNs), to provide Internet connection, packets originating from mesh clients are relayed through multihops by the mesh routers (MRs) towards the Internet gateway (IGW). As MRs may belong to different entities, in the aim to provide sufficient Internet throughput to its clients or avoid traffic congestion, a selfish MR fully or partially drops the relay packets oriented towards...
