Network management based on mobile agents

In Mobile Ad hoc Networks (MANETs) congestion occurs due to the packet loss and it can be successfully
reduced by involving congestion control scheme which includes routing algorithm and a flow control at the
network layer. In this paper, we propose to agent based congestion control technique for MANETs. In our
technique, the information about network congestion is collected and distributed by mobile agents (MA) A
mobile agent based congestion control AODV routing protocol is proposed to avoid congestion in ad hoc
network. Some mobile agents are added in ad hoc network, which carry routing information and nodes
congestion status.When mobile agent travels through the network, it can select a less-loaded neighbor node
as its next hop and update the routing table according to the node’s congestion status. With the aid of
mobile agents, the nodes can get the dynamic network topology in time. By simulation results, we show that
our proposed technique attains high delivery ratio and throughput with reduced delay when compared with
the existing technique.

Mobile Agents (MAs) have been proposed as a solution for distributed Network Management (NM). However, most MA-based infrastructures exhibit scalability limitations when data intensive management applications are considered. Therefore, we present three novel applications, tailored to transfers of bulk network monitoring data, in which MAs are used to perform data aggregation, acquire atomic SNMP table views and support selective retrieval of SNMP table objects that meet specific selection criteria. The proposed ...
