In such as a highly dynamic and open environment, it has become a challenge to deploy multiple context-sensitive services due to the unwillingness of service provider to share resources. This apprehension to share resources stems mainly from a lack of trust. Sometimes infrastructure plays pivotal role to solve this issue with dynamic access control to replace traditional static policies. But when it comes to effective resource sharing in an infrastructure-less environment we face problems such as poor storage and computational capability. In this paper, we have developed a lightweight and distributed trust model based on recommendation, which will guarantee that service providers can securely share an unlimited number of resources, limited only by their hardware and bandwidth limitations. The multi-hop recommendation protocol incorporates a flexible behavioral model to handle interactions during service sharing and usage. This protocol will also assess risk using recommendations from context-sensitive services, in the trust framework, to help ensure smooth access to resources and services.
