Wireless sensor network is one of the effective tools for data gathering in a variety of environments which has a lot of challenges. Controlling the congestion is one of the challenges that primarily depends on the way the large number of sensors in a network are organized and controlled. A group of nodes is called a cluster which sends information to the gateway through the cluster head. This structure...
We propose a Heterogeneous Multi Domain (HMD) architecture and protocols that uses ad hoc and cellular communications for enabling the exchange of information among users and smart environments. In particular, we focuss on the data communication and information diffusion related to tourism industry. Sensor's technology enables today the collection of various data related to the environment, such as...
In recent work it has been shown that the use of virtual coordinates or identifiers for efficient routing and data management has several advantages compared to the use of predefined addresses or geographical coordinates. However, these advantages only hold for single domain networks with limited mobility. In this paper, we discuss the challenges arising from using virtual coordinates for routing...
