The team orienteering problem (TOP) is a particular vehicle routing problem in which the aim is to maximize the profit gained from visiting customers without exceeding a travel cost/time limit. This paper proposes a new and fast evaluation process for TOP based on an interval graph model and a Particle Swarm Optimization inspired algorithm (PSOiA) to solve(More)
Ad hoc routing protocols have been designed to be more and more efficient without keeping security in mind. This makes them vulnerable to a variety of attacks which affect the reliability of data transmission. We propose in this paper a new a secure protocol based on the hash chains to provide a high level of security. The proposed protocol is analyzed(More)
