Performance analysis of routing protocol in WiMAX network

Abstract

Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Demand for such type of mobile broadband services and applications are growing rapidly as it provides freedom to the subscribers to be online wherever they are at a competitive price and other significant facilities such as increasing amounts of bandwidth, using a variety of mobile and roaming devices. The earliest version of WiMAX is based on IEEE 802.16 and is optimized for fixed and roaming access, which is further extended to support portability and mobility based on IEEE 802.16e, also known as Mobile WiMAX. However, frequent topology changes caused by node mobility make routing in Mobile WiMAX networks a challenging problem. This paper presented an analysis on those routing protocols especially designed for wireless networks. A study and comparison on the performance of three routing protocols (AODV, DSR, and DSDV) for Mobile WiMAX environment is done. An assumption of each subscriber station has its routing capabilities within its own network is prepared. The performance matrix includes Packet Delivery fraction (PDF), Throughput, End to End Delay, and number of packet dropped were identified. The study used NS2 simulator for the comparison on the performance analysis. Successfully results found that AODV protocol outperform the DSR and DSDV.

Varying Pause Time Effect on AODV, DSR and DSDV Performance

“…Considering a route for sending data is based on sequence number, a route having higher sequence number associated will be preferred for communication. Using routing table data and control information is transmitted throughout the network to transmit the updated information about the network topology and node status [11] [12] [13]. As DSDV is a proactive protocol, routing table need to be updated, changes in the network can also be managed by exchanging routing table between the all nodes.…”

“…In DSDV finding the least hop count route to destination from source is the major goal. Battery consumption is the major problem of proactive protocols because they always require battery in order to update routing table [12] [13].…”

An analysis and comparison of different routing algorithms in WiMAX networks

“…Here, hybrid means the algorithm which acts as both proactive and reactive. Recently, many researchers have focused on analyzing the different routing algorithms [2], [3], [6] in WiMAX network.…”
