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...

A capacitated location-routing problem (CLRP) is one of the new areas of research in distribution management. It consists of two problems; locating of facilities and routing of the vehicle with a specific capacity. The purpose of the CLRP is to open a set of stores, allocate customers to established deposits, and then design vehicle tours in order to minimize the total cost. In this paper, a ne...

The refugee crisis is one of the major challenges modern society. influxes refugees are usually sudden and in sheer need services such as health care, education safety. Planning public under an imminent humanitarian requires simultaneous strategic operational decisions. Inspired by a real-world problem that Red Crescent facing Southeast Turkey, we study locating camps planning transportation se...
