Jiter is referred as the variability of latency in packets over a period of time. In mobile network, topology changes rapidly which causes a reconfiguration of network. Therefore the latency of transmission also varies. It gives rise to a QOS problem as predicting exact latency is difficult. Hence time bound or real time packets can not be guaranteed highest QOS in MANET. It this paper we propose...
The multicast routing model is set up by hybrid routing protocol, Aiming at the mobile network topology and the characteristics of multicast routing based on QoS. A multicast tree meeting the QoS constraints, consumption tend to a minimum and stable form is set up based on ant colony algorithm. Experiments show that the algorithm has a better performance than the other algorithm.
As Wireless Sensor Network (WSN) applications become more popular in every day life, the importance of flexible communication protocols rises higher. The limited resources and time-critical nature of WSN must be addressed by the network layer, as one of the most mandatory communication components to support routing capabilities in multi-hop mobile sensor nodes' topologies. WSNs application particularities...
A distributed scheduling approach for fast deployable tactical IEEE 802.16e networks is presented where distributed base stations with dual radios form a mesh backhaul and mobile battle units communicate through these base-stations. The mesh backhaul is formed via an IEEE 802.16e mesh mode radio on each base station, while mobile units communicate with base stations via PMP mode radios. The scheduling...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
