Shruthiindbit@gmail.com Abstract:In Multi-hop wireless routing to successfully achieve high end to end throughput .To search a “best� node path from source node to the destination node .A large number of routing protocols use for minimum total transmission count/time for delivering a single packet, such transmission time minimizing protocols cannot be assured to successfully achieve maximum end to end throughput. Considering spatial reusability of the wireless media, increase the end-to-end throughput in multi-hop wireless network. To support a function in spatial reusability-aware Single path routing (SAAP) protocols, It compare with existing protocols, Results provide desired end to end throughputgain is up to 62.7%. and desired end to end delay. Keywords: Underwater resourceful routing, delay sensitive, energy cost.
