Alleviating Effects of Mobility on TCP Performance in Ad Hoc Networks Using Signal Strength Based Link Management

Tags:
tcp - ip

Overview Mobility in ad hoc networks causes link failures, which in turn result in packet losses. TCP attributes these losses to congestion. This results in frequent TCP retransmission timeouts and degradation in TCP performance even at light loads. This paper proposes mechanisms that are based on signal strength measurements to alleviate such packet losses due to mobility at light loads. The authors make changes at the MAC and the routing layers to predict link failures and estimate if a link failure is due to mobility. It also proposes a simple mechanism that can help alleviate false link failures that occur due to congestion when the IEEE 802.11 MAC protocol is used.

Peter Cochrane's Uncommon Sense: Why does technology fail?

In all complex systems a single point mechanism can lead to multiple failures and, conversely, multiple small failures can see a single dominant failure. Some generally unseen mechanisms can often lead to a cascade of technology failures as well.
