Unicast Bandwidth Efficiency Routing Algorithm for Mobile Devices (original) (raw)

2014 IEEE International Conference on Mobile Services, 2014

Abstract

Bandwidth is one of the characteristics that is used to measure network performance. In this paper, we present a Unicast Bandwidth Efficiency Routing Algorithm (UBERA) for mobile devices that are streaming video contents from a video server. The algorithm can adapt to different number of mobile devices with different level of mobility and different location. Routing decisions are based on the availability of the packet(s) within a given geographical location. The video server identifies the availability of the packets it has earlier sent to a particular client and requests the packet(s) to be forwarded to the requesting client. Real live video programme was streamed using VLC media player and the collected packets size and packet inter-arrival times were used in all the simulations. Different simulations were conducted using OPNET Modeler. After conducting series of simulation tests, the algorithm showed low server and network load, low delay, high adaptability and robustness.
