Post-disaster humanitarian relief is full of importance, complexity and difficulty, which makes people pay more attentions to various disaster measures emergency management practices related preventions reductions. The main purpose protect the lives victims in affected areas provide with indispensable materials survive from unexpected disaster. Therefore, this paper puts its focus on some key d...

parcel delivery is a complex logistic service, as it serves many small or medium-sized customers who may send or receive parcels. modeling such delivery system needs to integrate two different research areas of hub location and vehicle routing. as it totally depends on the network and the linkage of the nodes, in this paper, some door-to-door service providers are taken into account to provide ...

A Mobile Ad hoc Network (MANET) is an autonomous system of mobile stations connected by wireless link to form a network. It does not rely on predefined infrastructure to keep the network connected therefore it is also known as infrastructure less network. A designed protocol must provide scalable routing with better security. In this paper, we proposes the location based protocols of Dynamic Re...

We present geographical secure path routing, an infrastructure free geographic routing protocol, that is resilient to disruptions caused by malicious or faulty nodes. Geographic locations of anonymous nodes are authenticated in order to provide location authentication and location privacy simultaneously. Our protocol also authenticates the routing paths taken by individual messages. This provid...

Many ad hoc network protocols and applications assume the knowledge of geographic location of nodes. The absolute location of each networked node is an assumed fact by most sensor networks which can then present the sensed information on a geographical map. Finding location without the aid of GPS in each node of an ad hoc network is important in cases where GPS is either not accessible, or not ...

Most previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located. The significant communication overhead can be avoided if the routing strategy is changed. We propose that the source node issues several search 'tickets' (each ticket is a 'short' message c...

Privacy is needed in ad hoc networks. In order to provide anonymous routing protocol in MANETs the location of source and destination can be concealed by using “notify and go” mechanism and broadcasting. In this paper, we address some of the issues arising in MANETs by using an anonymous routing protocol. Location Based Anonymous Routing Protocol partitions the network into zones for anonymity ...

Wireless sensor networks are widely used in our daily life. It consists of various sensors which collect different information containing the identity, status, and location of an object or any other business, social or privately relevant information. But we pay attention to some issues related to sensor’s location privacy. In this paper, we focus on protecting the sensor’s location by introduci...
