Machine-to-Machine (M2M) technology is one of the key enablers of Internet of Things (IoT) vision which allows communication among smart things in the network and the back end system. Ensuring security through proper key management utilization is without a doubt an important requirement of any M2M system. This paper proposed a key management scheme based on the Elliptic Curve Cryptography (ECC) for...
Wireless Sensor Networks (WSNs) are used for monitoring and data collection purposes. A key challenge in effective data collection is to schedule and synchronize the activities of the nodes with global clock. This paper proposes the Synchronized Data Aggregation Algorithm (SDA) using spanning tree mechanism. It provides network-wide time synchronization for sensor network. In the initial stage algorithm...
The work aims at discussing possible engineering solutions to guarantee the interoperability between smartphones and WSN under high mobility levels. The paper discusses an application scenario where some of the most interesting standards for WSNs can be effectively employed together with smartphones. The architectures supporting interoperable smartphone/WSN systems, considering network topology and...
There has been a rapid growth of services based on session control. Session-based services comprise multimedia conferences, Internet telephone calls, instant messaging, and similar applications consisting of one or more media types such as audio and video. Deployment examples include session control services as part of the IP multimedia subsystem (IMS), in the third-generation mobile networks. High...
