Abstract: The data intensive industrial sensor networks produce excessive communication collision and introduce significant deficits. Further, a defined, appropriate scheduling methodology for transmission is desirable for mitigating the scarcity of such networks. With this declaration, here inclined a method for allocating conflict-free timeslots for transmitting the data in clustered sensor networks securing it from collision. This is lightened by partitioning the monitoring cluster regions into equal sized virtual grids and Latin square characteristics support scheduling in individual grids on ultra-wide band. This decentralised protocol follows an AODV routing and thereby each sensor is aware of the neighbouring nodes location and accepts the inherent topology changes. Moreover, the nodes that are participating in transmission remains in active state and the others become idle, thus conserving less energy. This distributed MAC scheduling method is particularly helpful in spatial usage of the communication channel for achieving scalability and efficiency and hence performance.
Keywords: MAC scheduling; performance enhancement; virtual grid; channel assignment; ultra-wide band.
