Scalability of Multi-Timeslot Allocation Protocol for WSN

Abstract: In wireless sensors network applications like habitat monitoring large-scale industrial monitoring & urban population monitoring require years of operation period with low rate data transmission. Providing a reliable data transmission & efficiency in energy usage are critical in order to prolong the network period of time. Our technique solves the problem's that commonly occurred in Wireless Sensor Network (WSN) like idle listening, overhearing & hidden terminal problem. By introducing a Time slotting communication mechanism, wherever node only transmits in its own timeslot & sleep in different timeslot if there's no activity. Proposed approach alleviates transmission collisions by using virtual grids that adopt Latin squares characteristics to time interval assignments. Proposed algorithmic rule derives conflict-free time schedules without incurring global overhead in scheduling.
