In the wireless sensor network there are several patterns of data forwarding interruption problems from the source to sink nodes in multi-hop path. In this paper, the authors propose a Dynamic MAC (D-MAC), energy efficient and low latency MAC for data gathering in wireless sensor networks. DMAC is designed to solve the interruption problem by giving the sleep schedule of a node an offset that depends upon its depth on the novel methods. DMAC also adjusts the duty cycles adaptively according to the traffic load in the network. They previously propose paper D-MAC protocol design methodology and presently the results is projected at self-learning, traffic adaptive algorithm for the WSNs.
