... attackers pose normal nodes during route discovery, and launch attack during data transmitting. (iii) Rushing [11]: This attack targets against on-demand routing protocols. T he attacker relays ... literature can be categorized into two main groups. (1) Table-Driven Routing Protocols, such as DSDV [1], and OLSR [2]. These protocols maintain a consistent and up-to-date route table to all...

In “Incomplete Game”, access delay performance is far better than “NM”, and comparable with “IBM”, as it can easily adapt the variable game ... no collision and low waiting time in backoff procedure. For “Incomplete Game” channel efficiency almost keep constant after 30 nodes, as each node can adapt to the variable game state and...

... maximum duration of HCCA in a beacon interval (T Beacon ), that is, a superframe. A basic weakness of the HCCA protocol is related with its nature. HCCA is an optional part of HCF that can guarantee QoS ... case the trafficloadis higher than BAU, then the traffic throughput equals BAU, as it is already explained. After calculating the throughput of each traffictype,we can estimate its ave...
