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, we 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. We previously propose paper D-MAC protocol design methodology and presently the results is projected at self-learning, traffic adaptive algorithm for the WSNs. The design incorporates contention based on CSMA/CA mechanism based timing for energy-aware sensing network to overcome this control overhead and latency. This protocol is simulated in Matlab and performance evaluated. Our simulation in Matlab shows that DMAC provides significant energy savings and latency reduction while ensuring high data reliability.
