Antenna System Strategies for Wireless Sensor Networks in Resource Hungry Smart Cities

The information and communication technology (ICT) backbone of any smart city system should be essentially a wireless sensor network (WSN) for it to be smart in any sense. It goes beyond doubt that such a system is extremely hungry in terms of information and resources. The vital resources like frequency spectrum, power of transmission, number of transreceivers etc. have their own set of limitations in terms of feasibility, availability, safety, reliability and cost-effectiveness. Here, major limitations of a wireless communication network are discussed. A strategy of smart integrated network service (SINS), using directive antennas and phased arrays is proposed to do away with most of these problems.
