A Light-Weight Channel Rendezvous Scheduling for Multi-Channel Medium Access in Sensor Networks

In this paper, the authors present an efficient channel rendezvous (i.e., sender and receiver communicate on the same channel) scheduling for multi-channel Medium Access Control (MAC) in Wireless Sensor Networks (WSNs). The proposed scheme mainly targets to implement an efficient medium access control that can cope-up and adapt with the mostly available dynamic and diverse traffic environments of WSNs. To do so, the duty-cycle (periodic wake-up and sleep under low traffic) and multi-channel (at heavy traffic) concepts are applied for the proposed channel rendezvous and medium access design.
