This paper proposes a novel Cross-layer Synchronous Dynamic Token Protocol (CLSDTP) in single channel that is based on token-passing scheme. The protocol introduces a token relay algorithm which is fast and adaptive to topology variation, presents a collision avoidance algorithm which solves the exposed and hidden terminal problem through the information of network topology and current data transmission...
Wireless sensor networks are conceived to monitor a certain application or physical phenomena and are supposed to function for several years without any human intervention for maintenance. Thus, the main issue in sensor networks is often to extend the lifetime of the network by reducing energy consumption. When the network topology does not change very often, a clustering technique can be used to...
This contribution proposes and investigates a random access Medium Access Control (MAC) - Relay Selection Mechanism - for cluster-based geographic routing in Multi-hop Wireless Sensor Networks (WSNs). The intertwined MAC and network routing solution is derived in a cross-layer approach. The game-theoretical relay selection strategy (random multiple access) relies on well-known descending pricing auctions...
