A New Power Saving Routing Algorithm For Delay Tolerant Networks
Delay tolerant networks (DTNs) are wireless networks with intermittent connections. Node mobility, limited radio range and power cause intermittency. These networks have different applications such as space searching, wild life tracking, military battlefields and etc. Conventional routing approaches are not practical in DTN because of intermittency. So, routing is a challenging matter. This pap...
متن کاملMaxHopCount: A New Drop Policy to Optimize Messages Delivery Rate in Delay Tolerant Networks
Communication has become a necessity, not only between every point on the earth, but also on the globe. That includes hard topography, highlands, underwater areas, and also spacecrafts on other planets. However, the classic wired internet cannot be implemented in such areas, hence, researchers have invented wireless networks. The big challenge for wireless networking nowadays, is maintaining no...
متن کاملVehicular Delay-Tolerant Networks
Vehicular Delay-Tolerant Networks (VDTNs) are composed of mobile nodes that communicate wirelessly with each other to forward data despite connectivity issues. This paper focuses on the problem of some nodes trying to impair the communication of a VDTN. In the paper we study the case of nodes that delay the forwarding of messages that is a particularly difficult to detect form of misbehavior. W...
متن کاملA delay-oriented prioritization policy based on non-congestive queuing
In this paper, we depart from our previously proposed Non-Congestive Queuing (NCQ) mechanism and propose a new scheduling discipline that allows for efficient interoperation of dedicated systems (such as sensor and voice networks) with the Internet. More precisely, our approach provides delay guarantees to applications that do not contribute noticeably to congestion because of their tiny packet...
متن کاملVehicular Delay-Tolerant Networks
—There are problems of low delivery radio and high transmission delay in Vehicular Delay-Tolerant Networks (a.b. VDTN. To address these problems, this paper proposes a Vehicular Delay-tolerant Network routing algorithm based on Contention (a.b. VDNC). VDTN algorithm consists of three strategies: the intersection selection strategy based on the Manhattan distance and traffic information, the fi...
