Monitoring Selfish Nodes in MANET during Replica Allocation
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 5
Abstract
Abstract: Mobile Ad Hoc Network is a collection of mobile hosts. The mobility nature of the MANET causes the mobile host to move freely in the network, due to that network disconnections occurs frequently and this causes frequent changes in the network topology. Data in one network cannot be accessed by the host in the another network, the data accessibility from one network to another network becomes impossible, consequently data accessibility become lower in the wireless network than in the conventional fixed network. This leads to performance degradation. Many Replica allocation methods are used to improve the data accessibility by replicating data item on mobile hosts other than the original owner of the data. This improves the data accessibility but some of the mobile hosts in the network may act as selfish nodes. These nodes use the services of other nodes but this does not cooperate with other nodes, this reduces the overall data accessibility. Selfish node detection algorithm is used to detect the selfish nodes and then the data replica allocation method is used for data replication. The simulation result shows that the conducted selfish node detection method and replica allocation techniques outperforms the improvement in data accessibility and reduce the communication cost and query delay
