Service discovery protocols are used to facilitate dynamic cooperation among devices / services with


minimal user intervention. These protocols work by exchanging messages to identify and locate the


relevant services. When new devices and services are added the flow of messages often appears as a


burst. These bursts act as a critical factor that may cause the loss messages which dramatically


influences the performance of the service discovery process. Thus, the loss of messages results in


uncompleted discovery process which will directly affect the sharing of resources in home networks.


This paper proposes an algorithm that computes the minimum period of time required between a


consecutive burst of messages and determines the minimum required queue sizes for the routers to


manage the traffic and avoid dropped messages. The algorithm has been applied to the Universal Plug


and Play (UPnP) protocol and considered the used of Active Queue Management (AQM). It was tested


when the routers were connected in two configurations; decentralised and centralised. The message


length and bandwidth of the links among the routers were taken into consideration. The result shows


better improvement in number of dropped messages `among the routers.
