Past studies in WSN have concentrated on data routing, energy efficiency, data latency and protocol development. In this paper, a low latency guaranteed time slot MAC protocol based on data priority with a bias for low energy nodes is proposed. The intelligent sensors collect event based data and polled data in a target area. The reduction in data latency is based on forwarding data packets which have a higher priority in a wireless network. DP-MAC (Data Priority-Medium Access Control) has been designed to address the data latency problem to ensure that emergency and hazardous events in a transportation network are reported with minimum delay.
