Wireless sensor network (WSN) possess energy, processing, computation, storage and communication constraints. To prolong lifetime of WSN, routing can serve a significant role in data delivery from source to sink. Many of the real-time sensing applications of large scale WSNs have heterogeneous sensor nodes scattered in a spatial region with different quality of service (QoS) requirements. Therefore, it is essential to design a protocol which guarantees desired QoS in heterogeneous WSN (HWSN). In this research work, firstly the parameters, challenges and performance metrics of QoS for WSN are discussed. A MAC layer protocol called stable topology based energy efficient protocol for distributed network (STEED) for HWSNs is proposed that is not only able to manage resources of nodes in heterogeneous environments but it is also able to maintain desired QoS. Simulation results reveal that STEED performs better in terms of stability and reliability than already proposed protocols.
