Improving Dynamic TDMA for Wireless Sensor Networks

Abstract

Dynamic TDMA is a multiple access control protocol that allocates specific time slots for each device/user to transmit or receive data (dynamically to those nodes which have data to send), providing predictable access to the communication medium. This mechanism has proven to efficiently reduce collisions during data transmission through Wireless Sensor Networks (WSNs). This paper aims to further enhance the existing Dynamic TDMA slot assignment protocol for WSNs by improving the algorithm that only allocates slots to nodes that potentially have data to send and then dynamically allocate variable length time slots, thereby, reducing vacant slots and increasing channel usage. The goal is to improve the current node detection algorithm by considering the other important factors, incorporating advanced node tracking methodology, and increasing the flexibility of the slot allocation process. © 2023 IEEE.
