Traditional gossip-based protocols rely on underlying routing protocols to disseminate messages. In mobile ad hoc networks, frequent topology changes may incur many route errors, which increase the overhead of maintaining routing information. They also need to maintain a partial or global view of the network, which further increases the overhead. This paper presents a broadcast gossip protocol based...
In recent years, various routing protocols have been proposed for ad hoc networks. Most of these protocols are based upon simulation and security. These protocols still lack in terms of performance efficiency of routing protocols such as avoidance of route breaking, sensing of breakage in route, security and reliability (basically authentication of mobile hops in the real ad hoc networks. i.e. during...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
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...
