Abstract:

Service discovery protocol is the key technology of mobile Ad-hoc network. This kind of protocol can find the location of the nodes and service automatically. The network topology is uncertain, and the service is difficult to be found in the network because the nodes are usually changed and moved in mobile Ad-hoc networks. To address these problems, some corresponding solutions are put forward. These methods can be divided into service discovery based on application layer and network layer, but they cannot effectively work. Based on the different characteristics of different protocols, it is feasible that these protocols are adopted in combination. However, multi protocol will lead to the problem of memory consumption and network information flow because of the heterogeneous nature of multi protocol. In this paper, a kind of service discovery framework based on component is adopted, which can be operated in a multi protocol environment. This fixed the heterogeneity problem of multi protocol and the framework is configurable and reconfigurable.
