This work shows prospects of application of transceiving stations with two antennas to provide an optimal routing in peer-to-peer mobile wireless networks. Route discovery for data transmission from source to destination is implemented by use of two antennas for signal reception at each station in the network. An optimal route discovery becomes possible due to detection of angular position of neighbors...
Node localization in mobile wireless sensor networks is a challenging task because of the changing environments and outlying sensor readings. A robust cooperative localization algorithm based on particle filter is proposed in this paper to deal with this non-Gaussian and non-linear estimation problem. Trace prediction, genetic crossover operation and node cooperation methods are used to optimize the...
Ad hoc networks in which nodes communicate via multi-hop, without wired infrastructure have been considered as excellent candidates for tactical military communications. In this paper, we present a routing scheme suitable for tactical networks, which combines zone routing protocol and backbone networks. With the introduction of backbone nodes, message to nodes outside of routing zone is relayed though...
Broadcasting is a common algorithm of on-demand ad hoc routing protocols for its simplicity and reliable accessibility. However, blind broadcasting often incurs collision, contention, and redundancy, which are called broadcast storms. As a countermeasure, we propose a conditioned broadcasting approach, by allowing each intermediate node decides whether to rebroadcast or not based on neighbourhood...
