Description
Summary:Internet of Things (IoT) aims at connecting people, things that are controllable via internet through a seamless integration that will improve the livability in the cities and communities. Several issues need to be addressed before IoT the way it has been envisioned, can exist. One of the issues will be spectrum scarcity due to high density of IoT devices. Considering the sporadic and multitudinous communication requirements of the IoT devices, an intelligent spectrum sharing mechanism is needed. Such mechanism must consider the heterogeneity of the IoT devices in terms of services offered and communication requirements. In this paper, Complex-Event-Processing (CEP) based Service-Prioritized Opportunistic Communication (SPOC) enabler is proposed that can act as a coordinator for the IoT devices. SPOC has a novel event driven spectrum management architecture for IoT network which facilitates the analysis and processing of spectrum demands in real time. SPOC acquires information about spectrum availability, spectrum demands, device abilities, service priorities and makes spectrum allocation decisions such that service completion rates are improved for all devices while providing reliable QoS to high priority services. Simulations show that compared to linear spectrum allocation schemes, SPOC can achieve high spectrum utilization while processing several thousands of spectrum demand requests. It also reduces waiting time while maintaining the fairness to all users.
