The use of wireless links causes several problems for TCP connections. Among them are high loss rates, high delay latency, high delay jitter, reverse path contention, dynamic link capacity, and link capacity dependent on transmission rate. These problems can be ameliorated through the use of modifications to TCP, with or without support from a router in the network. Solutions fall into two general categories: modifications which utilize an intermediate router with or without breaking the end-to-end semantics of TCP, and modifications which do not rely on any cooperation from routers. Solutions which utilize an intermediate router generally are more effective because they do not need to guess whether losses were caused by congestion or corruption.
