Routing Approach for P2P Systems Over MANET Network
share
Thanks to the great progress in mobile and wireless technologies, Internet-distributed applications like P2P file sharing are nowadays deployed over MANET (i.e., P2P mobile systems). These applications allow users to search and share diverse multimedia resources over MANET. Due the nature of MANET, P2P mobile systems brought up many new thriving challenges regarding the query routing issue. To tackle this problem, we introduce a novel context-aware query routing protocol for unstructured P2P mobile file sharing systems. Our protocol (i) locates relevant peers sharing pertinent resources for user's query and (ii) ensures that those peers would be reached by considering different MANET constraints (e.g., query content, peer mobility, battery energy, peer load). In order to consider all these constraints for choosing the relevant peers, we are based on the technique for order preferences by similarity to ideal solution (TOPSIS). We implemented the proposed protocol and compared its routing efficiency and retrieval effectiveness with another protocol taken from the literature. Experimental results show that our scheme carries out better than the baseline protocol with respect to accuracy
