  In wireless caching networks, a user generally has a concrete purpose of
consuming contents in a certain preferred category, and requests multiple
contents in sequence. While most existing research on wireless caching and
delivery has focused only on one-shot requests, the popularity distribution of
contents requested consecutively is definitely different from the one-shot
request and has been not considered. Also, especially from the perspective of
the service provider, it is advantageous for users to consume as many contents
as possible. Thus, this paper proposes two cache allocation policies for
categorized contents and consecutive user demands, which maximize 1) the cache
hit rate and 2) the number of consecutive content consumption, respectively.
Numerical results show how categorized contents and consecutive content
requests have impacts on the cache allocation.
