Wireless sensor networks (WSNs) serving in hostile environments are susceptible to multiple collocated failures due to explosives and natural calamities such as avalanches, landslides, etc., which can partition the network into disjoint segments. In such a scenario, federating the segments becomes essential for reestablishing communication among segments and resuming the WSN operation. Placing relays...
According to high-speed mobile nodes in UAV Ad Hoc network to bring the network topology changes frequently, link time is short, the network load increasing to bring the link layer congestion, and node energy is limited, and this paper puts forward a new routing protocol of MPEAOLSR (Multidimensional Perception and Energy Awareness OLSR). The node link time, link layer congestion and node residual...
To potentially alleviate the spectrum shortage for sensor networks of tremendous number of nodes, cognitive radio technology, and thus multi-hop opportunistic and concurrent transmissions overlaying with the primary system suggest an attractive facilitation of large-scale sensor networks. However, it is shown to result in significant end-to-end delay to prohibit practical applications. Noting the...
Beaconless georouting algorithms are fully reactive and work without prior knowledge of their neighbors. However, existing approaches can either not guarantee delivery or they require the exchange of complete neighborhood information. We describe two general methods for completely reactive face routing with guaranteed delivery. The beaconless forwarder planarization (BFP) scheme determines correct...
