The standardization of the IEEE 802.15.6 protocol for wireless body area networks (WBANs) dictates the physical layer and medium access control layer standards from the communication perspective. The standard supports short-range, extremely low power wireless communication with high quality of service and data rates upto 10 Mbps in the vicinity of any living tissue. In this paper, we develop a discrete-time...
In recent years, multimedia network services have moved from a single service to rich services which integrate multiservice capabilities integration. If all service requests require the user to send the request by himself, this will result to a huge control function load and complex service collaboration. In order to address service interaction and reuse the service capability, 3GPP proposes a Service...
This paper proposes a Friend-based security scheme for efficient routing in mobile ad hoc networks. The idea behind this technique is the establishment of friend networks in the same way as the formation of friends in real life scenarios. The algorithm provides authentication of nodes by sending challenges and creating friend lists of nodes that complete the challenge. Friends are rated on the basis...
