Performance Evaluation of Unified Index Hub Using Integrated Signature

Abstract

Due to its widespread application mobile computing has become reality. In real time broadcast, data management research community faces challenge from battery power and delay in data retrieval. The increasing populations of broadcast operator without widening the available electromagnetic spectrum worsen the situation. Index tree and signature techniques are generally employed to manage data in mobile environment. When similar type of data has broadcasted than signature technique is preferred over index tree technique for better data retrieval time. Lee and Lee model of integrated signature is effective in reducing access time. With many number of broadcast operators, the unification of operators is alternative way to manage data. The UIH developed by Verma S. et.al. is a way to unify the broadcast operators. This research work intends to propose a new model by applying integrated signature to UIH and compare the performance to state of art Lee and Lee model. The proposed model is simulated using Matlab7.4. The simulation result shows the proposed model out perform the existing state of art Lee & Lee model.
