Infrastructure-Based Wlan Routing Protocol Design

Most of the research work undertaken recently on the area of mobile computing, particularly on routing protocols topic, have ignored the truth that a significant number, possibly more than 50%, of the real-world implementation scenarios of wireless networking topologies are infrastructure based. To support this hypothesis, for instance, out of eleven research papers focusing routing protocols published in IEEE transactions on mobile computing from the year 2002 to 2005 ten were full concentrated in mobile Ad-hoc network (MANET).But according to [8], in many real-world scenarios Mobile Nodes can only communicate with access point (AP), not with other Mobile Nodes, and thus no need of deploying ad-hoc routing protocols as they tend to increase unnecessary network traffic. In this research work a new Infrastructure-Based Routing Protocol (IBRP) has been proposed. IBRP is a table-driven wireless routing protocol that (in contrast to DSDV, AODV and DSR) only supports direct communication between neighboring wireless nodes or between access point (AP) and mobile nodes. IBRP is not favor multi-hop wireless routing as it is not supporting forwarding of a packet through MNs, assuming all non-neighbor destinations to be unreachable and whenever wants to send packets destined to non-neighbor destination it channeled through AP.IBRP observed to operate efficiently in infrastructure wireless topology. In other words, IBRP seems to be a perfect solution for infrastructure wireless network routing mechanism by eliminates unnecessary network traffic overheads caused by using ad hoc routing protocols in implementing infrastructure based wireless networks. With comparison to another table-driven routing protocol, namely DSDV, designed for ad-hoc network, the study clearly indicates that IBRP routing protocol is superior to DSDV. IBRP proves to have lower delay than DSDV in higher mobility, it has observed to perform better with high throughput than DSDV as well as observed to have low overhead compared to that of DSDV.
