A team of robots (also called actors) in Wireless Sensor and Actor Networks (WSANs) may not be able to optimally cover an area so that after an event is reported by a sensor all robots may not be quickly reachable for possible action in time. Furthermore, sensors may not be able to immediately deliver a report to a nearby robot. In this paper, we focus on dynamic location service to deal with sequence...
Transmission Control Protocol (TCP) carries the maximum Internet traffic, so performance of TCP largely affects the performance of Internet. However, end-to-end throughput in TCP degrades notably when operated in wireless networks, since random packet losses and packet reordering are considered as congestion. In wireless networks, due to high bit error rate and changing level of congestion, retransmission...
In this paper, we propose a novel trust management scheme for improving routing reliability in wireless ad hoc networks. It is grounded on two classic autoregression models, namely Autoregressive (AR) model and Autoregressive with exogenous inputs (ARX) model. According to this scheme, a node periodically measures the packet forwarding ratio of its every neighbor as the trust observation about that...
We propose a localized address autoconfiguration (LaConf) scheme for wireless ad hoc networks. Address allocation information is maintained on the network border nodes, called addressing agents (AAs), which are locally identified by a geographic routing protocol GFG (Greedy-FACE-Greedy). When a node joins the network, it acquires an address from a neighboring AA (if any exists) by local communication...
