Mobile ad-hoc Networks (MANETs) are well-liked networks in all types of wireless networks. To transfer data in Mobile ad-hoc Networks, widely used protocol is Dynamic Source Routing (DSR). A field which plays very important role in data transfer is “Hop limit” which is applied in each Route Request message of DSR. It controls the propagation of Route Request according to a specific value which is mentioned in Time-to-Live (TTL) portion of IP header. Это и многое другое вы найдете в книге Performance Improvement In Routing For Mobile Ad-hoc Networks (Zain Ul Abiden Akhtar)
