When multiple nodes desire to transmit in a network, a set of rules generally known as routing and collision avoidance protocols are needed to avoid collisions and to retransmit lost data. We suggest a novel yet efficient technique for ADHOC network management using uniform Latin square matrix. Each entry of Latin Square Matrix is unique in row and column.(More)
