A discrete addressing scheme for Wireless Sensor Networks based Internet of Things

Internet of Things (IoT) paradigm is gaining a mountainous attention because of its noteworthy impact on everyday life of the people. Billions of things are expected to be a part of IoT paradigm in the near future, providing enormous applications ranging from home automation, smart environment, health care, etc. One of the major hurdles for IoT to be effective with existing network architectures is a prolonged and seamless connectivity between the things and with the end user. Due to heterogeneity in the characteristics of Wireless Sensor Network (WSN), it has become a most prominent technology to bind the things with the Internet and with the end users. Wireless Sensor Networks are self healing and active in nature, that is, they can sense, instruct, request, respond and can easily be adopted to Wireless Sensor and Actuator Networks (WSAN). Addressing scheme in Wireless Sensor networks has to be foreseen if it has to be deployed in Internet of Things paradigm. This paper proposes a discrete cluster based addressing scheme on IEEE 802.15.4 standard for all the things included in a Wireless Sensor Network based IoT applications. Results have been evaluated with existing IPv6 based addressing and it is found that cluster based addressing scheme on the traditionally used IEEE 802.15.4 communication channel suits well over the end to end IPv6 communication channel.
