A mobile based neighborhood watch system capable of group interactions, anonymous messages and observation reports. A disclosed method may include receiving an electronic document containing hierarchical data, memory layout information, and memory address information, wherein the memory address information comprises a base address. A resulting media channel is established so that the one of the calling home node and the called home node is not part of a path of the media channel thereby minimizing the total distance and delay of the media path. The error analysis algorithm further causes the memory controller to apply an erasure mode of the error correction code algorithm upon detection of a repeated pattern of data corruption across different addresses of the memory subsystem, and removes entries in the page deallocation table that correspond to data corruption addressed by application of the erasure mode.
