Energy utilization is a challenging task that is being encountered in low-powered Wireless Sensor Networks (WSNs) when designing an algorithm, protocol or hardware. Congestion is a factor that can affect a network's lifetime (and energy utilization), since it usually leads to packet drops or collisions in the medium followed by possible retransmissions. Forwarding data packets through alternative...
Unlike traditional routing schemes that route all traffic along a single path, multipath routing strategies split the traffic among several paths in order to ease congestion. It has been widely recognized that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. Yet, most studies in the context of multipath routing focused on centralized...
InfiniBand networks are aimed to fulfill increasing communication demand of parallel applications in high performance clusters. However, the dynamic behavior of communication load may cause bottlenecked link(s) which lead to message congestion. Congestion spreading increases latency and reduces network throughput causing important performance degradation. In this paper, we propose a congestion control...
Recent developments on the directional antennas have given a new dimension to revisit the problem of how to design more efficient topology formation and control protocols for a wireless mesh network (WMN). The WMN can be thought as the commercial extension of mobile ad hoc networks, forming a wireless multi-hop backbone network with static nodes such as mesh routers. Topology control is required by...
