[ns] Simulating noise/interference in WLAN

Dear ns2-users, We are using ns2 for simulating an infrastructure mode 802.11 wireless network. We have the following questions. 1. We tried creating a BSS with a single AP(node_(0)) and two mobile nodes ((node_(1) and (node_(2)). TCP traffic was setup from node1 to node2. We expected the

[ns] Simulating channel Hopping in ns2

Hi all, We intend to implement channel hopping using ns2 simulator. Has anyone tried to implement hopping in ns2? Our approach: We found that each channel (class WirelessChannel) keeps a linked list of all nodes listening on that channel. For a mobilenode to hop we wrote code to dynamicall
