ABSTRACT
Hybrid protocol combines the advantages of proactive and reactive routing in adhoc network. The routing is
initially established with some proactively prospected routes and then serves the demand from additionally
activated nodes through reactive flooding. In this paper we propose A Quality Hybrid Service Discovery Protocol
(QHSDP) for discovering services. A broadcast mechanism is used to get the service and routing information of
the nodes present inside the zone. The routing and service information reduces the packet flooding in the network
hence reducing collision and increasing packet delivery efficiency. Reduced control packets in turn reduces the
battery power consumption. A query message is bordercasted through the peripheral nodes to the nodes outside
the zone. This makes the discovery procedure more sclable, hence increasing the node’s coverage and reducing the
latency in the proposed technology compared to the existing technology.
