The demand for real-time applications in WSN is increasing day by day. For the different WSN a based QoS
requirement (e.g. bandwidth and delay constraints) raises significant challenges. Designing a data gathering algorithm in WSN for
the needs of application/users raises an issue of energy at sensor node. While providing precise QoS guarantee, the networking
protocols need to cope up with energy constraints. In many applications such as multimedia applications, or real-time and mission
critical applications, the network traffic is mixed of delay sensitive and delay tolerant traffic. Enabling QoS in sensor networks
requires energy and QoS awareness in different layers of the protocol stack. Energy Efficient and QoS aware multipath routing
protocol(EQSR) that maximizes the network life time through balancing energy consumption across multiple nodes, uses the
concept of service differentiation to allow delay sensitive traffic to reach the sink node within an acceptable delay, reduces the end
to end delay through spreading out the traffic across multiple paths, and increases the throughput through introducing data
