DSP-IR: Delay Sensitive Protocol for Intelligent Routing with Medium Access Control

The wireless sensor network has been positioned itself from a complete network system to a sub-net of future internet namely Internet of Things, where a communications among anything to anything is possible. The extensible use of wireless sensor network makes it more risky if the security threats are not handled wisely. The conventional methods adopted for securing the WSN vulnerability based attacks introduces delay, which brings congestion in the routing flow as well as influence the quality of service. The proposed DSP-IR is a secure routing algorithm to handle security with delay sensitivity. The DSP-IR framework evaluates MAC protocols including S-MAC, Q-MAC and IH-MAC along with RSA, AES and DSP-IR encrypt process. For all the three combinations performance evaluation is done by simulating the model to know the behavior of residual energy, energy consumption and average packet delay with varying interval of message arrival time and it is found that the proposed IH-MAC with DSP-IR exhibits better performance.
