Authenticated Reliable and Semi-reliable Communication in Wireless Sensor Networks

Secure communication in wireless ad hoc sensor networks is a major research concern in the networking community. Especially the few available resources in terms of processing power and available memory are challenging factors. Additionally, a typical characteristic of wireless ad hoc sensor networks is the error-proneness and, therefore, the unreliability of communication paths. In this paper we describe a new approach and an according protocol for usage in ad hoc networks that provides reliable as well as semi-reliable communication services in combination with security services. Thus, the proposed methodology allows to ensure data integrity and message authentication. The main aspects during the development were the limitations of typical sensor nodes used in ad hoc networks in terms of available storage, processing power, and energy. Our solution provides the capability of acknowledging correct receptions as well as the check of data integrity and message authentication in a single...
