solvable graphs (also known as reachable graphs) are types of graphs that any arrangement of a specified number of agents located on the graph’s vertices can be reached from any initial arrangement through agents’ moves along the graph’s edges, while avoiding deadlocks (interceptions). in this paper, the properties of solvable graphs are investigated, and a new concept in multi agent moti...

Due to the resource constraints on sensor networks, many recent key management schemes exploit the location of nodes in order to establish pairwise keys. Despite these efforts, location discovery for sensor networks is very difficult, because existing schemes have failed to consider changes in the signal range and the deployment error. As a result, network performance may accidentally decrease,...

Wireless sensor network is identical with low-power thus communication establishment must consider energy constraint. As a consequence, secure data dissemination over sensor networks is a difficult challenge, considering that establishing secure link and transmitting secure data requires additional resources which may give shortage to network lifetime. This paper offers an alternative to secure...

Communication protocols issues are one of the effective factors in communicated networks performance. One of challenging problem in CMT-SCTP which sends data by multipath concurrently is Receive Buffer Blocking. This problem has important role in data transmission speed in computer networks. In this paper, we propose a control method based on fuzzy logic so that can solve Receive Buffer Blockin...

Internet in today’s world has become one of the most prominent ways to communicate through text, voice, pictures, video and many more ways. Millions of MB of data is exchanged over internet in a single day all over the world. And lots of those data is sensitive and private. Thus internet provides as point to intrude in someone’s private life or intercept some sensitive data. With the increasing...

forest road construction is the most costly operation in forestry. road designing and construction in unsuitable areas may increase construction and maintenance costs and also cause many environmental impacts. therefore, it is required to pay more attention to forest road design. in this research, we tried to introduce an appropriate method for locating forest roads using gis and ahp simultaneo...

Security and privacy are fundamental prerequisites for the deployment of vehicular communications. The neardeployment status of Safety Applications for Intelligent Transport Systems (ITS) calls for strong evidence on the applicability of proposed research solutions, notably close-to-reality situations and field-operational trials. The contribution of our work is in this direction: We present a ...
