Afetlerin ne zaman ve nerede meydana geleceği belli değildir. Bundan dolayı hem toplumsal yaşam kesintiye uğramakta de çevreye zarar vermektedir. Ayrıca, afet sonrası insanların yiyecek, barınma, temizlik gibi ihtiyaçları hızlı düzenli bir şekilde karşılanmalıdır. Deprem büyük zararlara neden olan birçok yeri kullanılmaz hale getiren afetlerde ihtiyaçlarını karşılayabilmek için geçici deponun k...

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...

Disasters such as earthquakes, typhoons, floods and COVID-19 continue to threaten the lives of people in all countries. In order cover basic needs victims, emergency logistics should be implemented time. Location-routing problem (LRP) tackles facility location vehicle routing simultaneously obtain overall optimization. response shortage relief materials early post-disaster stage, a multi-object...

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...

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...
