An End-to-End Delay-based Scheduling Algorithm in IEEE 802.15.4e Networks

This paper proposes a novel scheduling algorithm using multi-channel and multitimeslot with the objective of reducing the end-to-end (e2e) delay in a tree-based wireless sensor network. The algorithm exploits a staggered timeslot allocation in terms of e2e paths, rather than the one with individual branches. It also increases simultaneous data transmissions. The proposed algorithm is shown to be superior to an existing algorithm with non-e2e delay based, in terms of e2e delay.
