THESEUS: A Routing System for Shared Sensor Networks

THESEUS is an energy-efficient routing system for Shared Sensor Networks (SSNs), with the primary goal of extending network lifetime. THESEUS has two features that distinguish it from other works found in the literature. First, it saves SSN nodes energy by using a packet aggregation algorithm, which reduces the number of transmissions. Second, THESEUS balances energy usage in the whole SSN by its dynamic, QoS and energy aware route selection algorithm. Such energy usage balancing avoids network partitioning. Both features of THESEUS result in prolonging the SSN lifetime. Experiments were performed with the purpose of evaluating THESEUS effectiveness for improving the SSNs lifetime. Furthermore, THESEUS supports multiple sink nodes dynamically that means it adjusts routes in case of a sink node added or removed.
