Priority based QoS protocol for heterogeneous traffic routing in WSN

A new routing protocol that adjusts of the necessities of heterogeneous traffic is presented in this paper. The proposed scheme make improvement in TeGAR algorithm. The point of the scheme will be on accomplish low latency, and to fulfill various quality of service (QoS) in different network conditions. To do that, the proposed algorithm exploits multiple nodes' attributes like distance to the Sink, energy, history of nude delay of data to neighbors and probability of link availability to determine the best node for delivering different traffic necessities. The contribution of the proposed algorithm is its capability to distinguish the data-related to every type of traffic and give various priorities to various data categories so that every type of traffic categorization assures to meet the requirements of the application necessities. The results show that the proposed protocol outperforms TeGAR.
