Abstract
With the growth of advanced networking technologies and capable terminals, it is very convenient for mobile operators to develop new service contents for mobile phones such as mobile Internet services, mobile television, and context-aware mobile services. Meanwhile, peer to peer (P2P) technology has made great success in multimedia services in the fixed networks such as Skype, PPlive, and Sopcast. Besides, demand for using P2P applications over PDAs and smartphone is increasing. So that, mobility in P2P networking has become a popular research area in recent years. However, mobile environment is different from the fixed networks in that it is limitation for process capability, memory, battery of mobile terminal, intermittent nature of wireless link and high churn rate of mobile users. In this paper, we focus on study drawbacks of Chord DHT algorithm in mobile environment. After that, we propose a mechanism for improving performance of Chord DHT algorithm based on the idea that is immediately stability of network topology when there is any node joining and leaving the network. Our simulation results show that our algorithm is better than previous studies about performance improvement of Chord DHT in mobile environment.
