we have problems when using device on windows compact framework 2.0 (windows mobile) , server iis (7) on windows server 2008 r2. on wifi.
we encounter many problems of latency , freezing. our app pretty simple. send small request (a string of 10 chars) server respond string of same length. there request device server every 3 or 4 seconds.
it works times , freeze. other clients environment : things vary network (not device or server both tested separately , , perform on wired network).
we using tcp , read not work on wifi packet loss not due same reason when on wired network (congestion).
does had freezing problems on tcp on wifi ? think pointed out same problem (tcp on wifi) ?
we change protocol used. first thing try tcp westwood.
is tcp westwood not offered on windows server , windows mobile ? if yes, how activate ?.
our last solution build our own server , protocol using udp. it's hard work.
thank answering.
try setting tcp_nodelay socket option sending small chunks less 1500. improve performance in lossy network.
