To reduce the complexity of scheduling while exploiting the advantages of TDMA-based data collection, we propose TKN-TWN, a token-scheduled multi-channel data collection protocol. The TKN-TWN uses two tokens to arbitrate data-packet transmissions and associates the ownership of tokens with transmission slot assignment. For the reduction of scheduling burden, the TKN-TWN provides topology adaptability...
A Time Synchronization algorithm based on Cluster for WSN was Proposed for WSN (Wireless Sensor Network)- CSSN (Cluster-based Time Synchronization for WSN). The algorithm involved two phases: In the Cluster-inter synchronization phase, it adopted pair-wise packet exchange mechanism to finish the time synchronization between the Base Station and cluster heads through establishing a hierarchical topology...
Low-latency data delivery is an important requirement for achieving effective monitoring through wireless sensor networks. When sensor nodes employ duty cycling, sending a message along the shortest path, however, does not necessarily result in minimum delay. In this paper, we first study the lowest latency path problem, i.e., the characteristics of a path with minimum delay that connects a source...
