"AUCTIONBOT:An implementation of static software agents"
by Sharath K Udupa, Prashanth Mekara and Akshay, SJCE, Mysore
ABSTRACT
Intelligent agents are software entities that carry out some set of operations on behalf of a user or another program with some degree of independence or autonomy, and in so doing, employ some knowledge or representation of the user's goals or desires. Agents continuously perform three functions: perception of dynamic conditions in the environment: action to affect conditions in the environment: and reasoning to interpret perceptions, solve problems, draw inferences, and determine actions.
Auctionbot is an agent that automates the user action of bidding at auction sites and helps the user to buy the required item at a lesser cost. The user provides the agent with information regarding his loginID at the different auction sites, the item he is intesrested in, maximum bidding amount and the algorithm strategy that it should follow in order to increment its bidding.
we propose to create separate agent servers at each site and make communication between the agents and the agent servers using TCP/IP sockets, i.e. agents here do not travel but exchange information about the bidding status at each site. The agent starts bidding on behalf of the user at that site, which has the least price. The exchange of information between auction agents and Agent servers sees to that the product is bought at the cheapest price.

ABSTRACT
A satelite link is characterized by a relatively high bit error Rate (BER) as well as high Round Trip Time (RTT). These properties of the link cause the TCP protocol to perform quite inefficiently due to frequent timeouts, as errors in the satellite channel are wrongly assumed to be due to congestion in the network.
In this paper, we present a modified protocol to improve the performance of TCP over satellite links. We suggest a mechanism where Explicit Loss Notification (ELN) traditionally used for wireless communication is modified for use in the satellite domain. Moreover, in order to handle multiple losses, the Selective Acknowledgements (SACK) techniques are incorporated with ELN. Results obtained based on a simulation study, show a marked improvement in performance using this modified protocol when compared with traditional TCP mechanisms.
