This paper focuses on coalescing sensor networks and mobile robots to provide a significant leap forward in technology by maintaining a self-organizing, ad hoc wireless network for environmental monitoring, military applications and rescue operations. Low-power sensor nodes are used to detect an event and guide mobile robots to such locations. These robots(More)
In this paper, we present the combined character segmentation algorithm based on the active contour model and nonlinear diffusion techniques. The active contour model is used to perform segmentation of printed characters. The coherence enhancing diffusion technique is proposed to smooth out artifacts and background noises without destroying the edges. The(More)
Wireless sensor networks usually comprise of a large number of nodes which are geographically distributed and are not physically connected. These nodes are frequently used to sense private data and can be necessary to transmit confidential and critical data. Hence it is important to provide security for wireless sensor networks. Research is still ongoing in(More)
