Abstract:
Secure data transfer (SDT) in wireless networks is required with minimum overhead. The SDT was done historically through cryptography, authentication, and probability based approaches. Collaborative approach for trust-based packet transfer is new to the wireless sensor network research. In the proposed research, trust value of a node is continuously updated using Sporas formula and repeated trust calculations. The average of these two provides the trust value of a node. The suspicious node will be informed to the neighbor nodes. Further, the neighbor nodes calculate their own trust of a suspicious node using its trust value plus trust factor received from their neighbor. The cooperative and collaborative approaches eliminate the suspicious node from the path quickly and confidently. The results show that the new approach is better than simply using the cooperative way or collaborative approach using Sporas formula.
