Abstract. Expanding Ring Search (ERS) is a prominent technique used for information discovery in multi-hop networks where the initiator of search is unaware of any of the ? locations of the target information. ERS reduces the overhead of search by successively searching larger number of hops starting from the location of search initiator. Even though ERS reduces overhead of search compared to flooding, it still incurs huge cost which makes it unsuitable especially to energy constrained networks like Wireless Sensor Networks ( ...
