ALOHA happens to be one of the simplest yet effective techniques for simultaneous data transmissions where the bandwidth is limited or for ultra low band (UNB) systems. ALOHA is protocol which can be used in several Internet of Things (IoT) based applications. ALOHA is basically a protocol (set of rules) which helps in transmission of data packets from several stations in a packet switched network. This WORK proposes a channel load sensing algorithm for Slotted ALOHA so that the channel is sensed and colliding conditions are investigated. The performance of the system is to be evaluated based on the arrival rate and throughput of the proposed system.
