Recently, geographic routing in wireless networks has gained attention due to several advantages of location information. Location information eliminates the necessity to set up and maintain explicit routes, which reduces communication overhead and routing table size. These advantages allow scalability especially in dynamic and unstable wireless networks. However, no matter which technologies o...

The Tor network provides low-latency anonymous communication to over two million users daily. To be practical for widespread use, Tor uses onion routing, which does not protect a user against an adversary that can observe a user’s traffic at certain vulnerable positions along the traffic’s route through the Internet. A natural defense would be to choose Tor relays to minimize the chance that th...

We propose probabilistic location to enhance the performance of existing peer-to-peer location mechanisms in the case where a replica for the queried data item exists close to the query source. We introduce the attenuated Bloom filter, a lossy distributed index. We describe how to use these data structures for document location and how to maintain them despite document motion. We include a deta...

Sensor networks are wireless adhoc networks where all the nodes cooperate for routing messages in the absence of a fixed infrastructure. Non-flooding, guaranteed delivery routing protocols are preferred because sensor networks have limited battery life. Location aware routing protocols are good candidates for sensor network applications, nevertheless they need either an external location servic...

A mobile ad hoc network (MANET) is a characterized by multi-hop wireless links, absence of any cellular infrastructure, and frequent host mobility. Existing MANET routing protocols are divided into location-aware and non-locationaware routing protocols. In a location-aware routing protocol, location information can be exploited to facilitate routing. Our protocol, namely multi-eye spiral-hoppin...

This paper presents a routing optimization model for wide range of waste collection problems which allows multiple depots with homogeneous, capacitated vehicles, intermediate stops at processing facilities, and pick-ups per location. By minimizing vehicle investment costs, the estimates total transportation costs given network design volumes to be collected different demand points. The number f...

Several applications of mobile ad hoc networks select geographical routing especially the Greedy Perimeter Stateless Routing (GPSR) protocol due to its scalability, efficiency, and ability to support location based applications. However, there are many security issues in protecting location information, which can easily be abused by attackers. Location based adversarial activities affect the op...
