Abstract
Minimization of delay in data collection at base station is one of the major concerns in cluster based Wireless Mesh Network. There exists few other techniques for the cluster head selection in wireless mesh network such as selecting a node with maximum energy as a cluster head. In this work, We consider dynamic nodes with single hop topology with in the static cluster. To minimize the delay that occurs in transmission and reception of data, the proposed model includes four modules namely, Cluster head selection, slot allocation, slot scheduling and data collection process. In proposed model, cluster head selection is based on the maximum energy, number of links and link duration. Link duration is considered in order to avoid the link breakage that occurs before the transmission of data. Slot allocation is based on the available energy [E avail) and the required energy (E req). Slot scheduling is carried out based on the link duration. A node with minimum link duration will be given higher priority to avoid re-transmission that indirectly results in minimization of delay. Data at the base station will be collected as they are scheduled. Mathematical model of the proposed model is presented in this work and it shows that proposed model minimizes delay compared to the existing there by improving network efficiency.
