Cooperation among nodes is fundamental for the operation of mobile ad hoc networks (MANETs). In such networks, there could be selfish nodes that use resources from other nodes to send their packets but that do not offer their resources to forward packets for other nodes. Thus, a cooperation enforcement mechanism is necessary. Trust models have been proposed(More)
In this paper we estimate the end-to-end total bandwidth (BW) and available bandwidth (ABW) of a path between a pair of nodes in an IEEE 802.11b ad hoc network, both as functions of packet length, using dispersion traces between probing packet pairs of different lengths. The pairs of packets that suffer the minimum delay are used to estimate the maximum(More)
To my parents José Arnoldo Alzate and Fabiola Monroy Everything I have achieved has been possible because of your unconditional love i SUMMARY In a wired multihop path, the concepts of end-to-end bandwidth (BW) and end-to-end available bandwidth (ABW) are clearly defined and widely accepted as the capacity of the narrow link and the unused bandwidth of the(More)
