Abstract : The purpose of this paper is to introduce certain models of topology -selective stochastic jamming and examine its impact on a class of fully-connected, spread-spectrum, slotted ALOHA-type random-access networks. The theory covers dedicated as well as half-duplex units. The dominant role of the spatial duty-factor is established, and connections with the dual concept of time-selective jamming are discussed. The optimal choices of coding rate and link-access parameters (from the user's side) and the jamming spatial fraction are numerically established for DS and FH spreading.
