Several atypical hierarchical routing protocols have been proposed among which grid-based routing protocols are an efficient way of disseminating data towards a mobile sink. The network is partitioned into a virtual equal-sized grids. The proposed protocol, Mode-Switched Grid-based Routing (MSGR) for Wireless Sensor Networks selects one node per grid as the Grid Head. The routing path to the sink...
A Wireless Sensor Network (WSN) consists of enormous amount of sensor nodes. These sensor nodes sense the changes in physical parameters from the sensing range and forward the information to the sink nodes or the base station. Since sensor nodes are driven with limited power batteries, prolonging the network lifetime is difficult and very expensive, especially for hostile locations. Therefore, routing...
